Answer:
Photosynthesis: the absorption of CO2 from the atmosphere (terrestrial plants) and from oceans (marine plants) to produce organic carbon structures.
Respiration: the release of CO2 into the atmosphere, soil and oceans by animals as they exhale.
Why is phosphorus a limiting growth factor in terrestrial ecosystems?
Answer:
Because the quantities of phosphorus in soil are generally small, it is often the limiting factor for plant growth. ... Phosphates are also limiting factors for plant-growth in marine ecosystems, because they are not very water-soluble. Animals absorb phosphates by eating plants or plant-eating animals.

#BRAINLESTPhosphorus is a limiting growth factor in terrestrial ecosystems because the quantity of phosphorus in soil are generally small it is often the limiting factor for plant growth.
What is the use of phosphorus in ecosystem?Phosphorus-based fertilizers boost the growth of plants on land, phosphorus in the ocean increase the production of microbes and small marine plants called phytoplankton, which compose the base of the marine food chain.
Phosphorus, like nitrogen, is a critical nutrient required for all life. The most common form of phosphorus used by biological organisms is phosphate (PO4), which plays major roles in the formation of DNA, cellular energy, and cell membranes (and plant cell walls). Phosphorus is a common component in commercial fertilizers.
We can say that phosphorus are very important factor for plant-growth in marine ecosystems because they are not soluble in water.
Therefore, Phosphorus is a limiting growth factor in terrestrial ecosystems because the quantity of phosphorus in soil are generally small it is often the limiting factor for plant growth.

Which of the following proteins could be used in connective tissues, tendons, or hair?
Answer:The answer is B
Explanation: I did the test and it was correct
Collagen fibrous protein
option (B)
What protein is found in connective tissue?Connective tissue that provides support and framework for the body consists of fibrous proteins and nonfibrous ground substances in varying proportions depending on their functions.
Collagen, which is the most abundant protein, constitutes about one-third of all body protein.
Do proteins provide support for connective tissues?These fibers hold connective tissues together, even during the movement of the body. Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that after being stretched or compressed, it will return to its original shape.

warm water from a nuclear power plant causes overgrowth of algae.
a river floods and deposits tree pollen along its banks.
Explanation:
Ecosystem consist of biotic and abiotic elements. Biotic refers to all living organisms while abiotic refers to all non-living elements of the environment. Living organisms depends on abiotic factors such as light, temperature, water and soil etc for their growth and survival. In the above answer, Ash of volcano, warm water and rivers are abiotic elements while plant, algae and pollen are biotic elements.

O A. The nervous system signals the endocrine system to release
hormones in response to a stimulus.
O B. The nervous system responds to a stimulus, and the endocrine
system returns the body to a relaxed state.
O C. The endocrine system signals the nervous system to send out
nerve impulses in response to a stimulus.
D. The endocrine system responds to a stimulus, and the nervous
system returns the body to a relaxed state.
The nervous system usually signals the endocrine system to release hormones in response to a stimulus. The correct option is A.
What is endocrine system?The endocrine system, which is made up of all of the body's different hormones, regulates all physiological processes in the body from gestation through adulthood and to old age.
This regulation also include brain and nervous system development, reproductive system growth and function, metabolism, and blood sugar level.
The endocrine system and the nervous system collaborate to influence many aspects of human behavior, together with growth, reproduction, and metabolism. And the endocrine system is crucial in the regulation of emotions.
In response to a stimulus, the nervous system basically signals the endocrine system to release hormones.
Thus, A is the correct option.

4) Discuss how our lives on Earth are directly related to our relationship and positioning with the Sun in our Solar System.
Answer:the relationship with the sun and the solar system is the same relationship to all physical bodies in which we are living at a speed governed by our perception at our vantage point in relation to how much gravity is acting upon us. Example: Say you were to fall into a black hole. At the point of no return at the event horizon your time would begin to slow down as seen from an outsider watching you fall. This will occur until to that observer sees you stop entirely in time. You however fall faster as faster but for ever. Till time is over. So all things are relative to each other in only one absolute way. Gravity control observed time.

Answer:
Invasive species in time destory biodiversity of an ecosystems
Explanation:
So lets go over what each answer is:
Invasive species are species that invade a ecosystem, and can harm other species and take over resources.
Populatiuons are what make up an ecosystem. There are many populations in a single ecosystem.
Biotic factors are the living things found in the world.
Abiotic factors are the opposite, being the nonliving things found in the world.
Looking at these, which would eventually destroy the biodiversity(variation of species) of an ecosystem?
This would be invasive species, for it is the only answer that harms it's ecosystem.
And this is correct, for invasive species often times can cause extiction of species, or even whole ecosystems.
For example of an invasive species, if a tree-consuming and widly reporudcing insect that lives in plains, invades a pine forest, it will eventually kill off all the trees in the area.
This wont only kill off the pine trees, but harms and could potentiallu kill the species that depend on the pine trees for survival.
Answer: invasive speices.

When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.

Which of the statements regarding the nitrogen cycle is true? a. Denitrification occurs when a nitrogen containing compound is produced from nitrogen in the soil. b. Atmospheric nitrogen is absorbed through the leaves of plants. c. Nitrogen fixation is the process atmospheric nitrogen is converted into biologically usable forms. d. Animals obtain nitrogen through the process of cellular respiration
Answer: Option C
Explanation:
The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.
Then from animals and human beings it is again transferred into the soil and then atmosphere.
The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.
