Describe the process of decomposition. (hurricane sandy 2012)

Answers

The decomposition is a process that occurs when the organisms are dying. The process stars shorty after the death of the organism. The decomposition occurs by abiotic and biotic processes, with the abiotic happening through hydrolyses, while the biotic happening because of the microorganisms. This process is part of the nutrient cycle, and it is crucial for the recycling of the finite matter. The decomposition is also what has enabled the formation of the soils, as the soils are a mixture of sediments and decomposed biomass.

What is the origin of the energy that all organisms need to carry out life functions?
A. food
B. producers
C. plants
D. the Sun

Answers

D the sun because it is the main leading producer for all living organisms

Answer:

D. The  Sun

Explanation:

The Sun is the major source of energy for organisms and the ecosystems of which they are a part.  This process begins the flow of energy through almost all food webs. Food is sunshine stored in chemical form. Organisms use the stored energy in food to fuel all living processes.

Explain why a food web is a more realistic model of energy flow than a food chain. 3 to 5 sentences.

Answers

Answer:

It includes more organisms in the ecosystem that would otherwise not be shown in a food chain.

Explanation: Food chains show just a single feeding pattern. Each organism has a single role in the ecosystem. Food chains make it easier to visualize trophic levels, or how energy moves through the ecosystem. This is why webs are considered to be more realistic than simple food chains.

Answer:

it includes more organisms in the ecosystem that would otherwise not be shown in a food chain. is right

Explain the flow of energy from the sun to sunflower and then on to a cardinal that ate the sunflower seeds. How did the energy help all three of these organisms to stay alive?

Answers

Answer:

The energy from the sun moved in the form of Light radiation, which the Sunflower then used in a process called photosynthesis. They use this to make sugar and that's what grows the seeds. This is then eaten by the cardinal, who uses it as chemical energy to fuel itself. The flower is growing from the energy that the sun gave off, and the cardinal recieves energy from the seeds.

The test: To understand if the ACTN3 protein affects running ability, researchers conducted a test. They recruited a group of competitive runners and measured the level of ACTN3 protein molecules each runner had in their bodies. Then, they had the runners participate in a sprint (a short-distance run). During the test, the runners sprinted as fast as they could for 100 meters.
Evidence: Scientists found that the runners who sprinted the fastest had the highest amount of ACTN3 protein molecules in their bodies.

Do you think that this evidence shows that the ACTN3 protein determines running ability? Explain your ideas using the words protein, trait, and feature in your response.

Answers

Answer:

The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. ... Although having one or two variant forms of the ACTN3 gene does not have any harmful effect, an individual's ACTN3 genotype does affect their athletic ability.

Think about the climate that you live in. How does your climate relate to the air and ocean currents?

Answers

Answer: Ocean currents can affect the climate of nearby land. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer. Places near the ocean experience moderate temperatures year round due to the fact that water has a high specific heat, meaning that it cools and warms slowly. Places further inland have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Ocean currents influence rainfall patterns. Warm, moist air associated with warm ocean currents increase precipitation.

bye im too lazy for this

Answer:

If you are closer to a ocean current, you can experience moderate temperatures year round because the water has a  specific temperature. his would make the land near the ocean take longer to heat up and cool down. Ocean currents affect the climate of the land near it. They move warm and cold water currents around the globe. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer.  Places further from the coast have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Of course weather you are closer or further also changes things. If you are closer to the equator you have higher temperatures, and the further away you get, the colder it gets. Ocean currents also influence rainfall patterns. Perspiration normally happens near the ocean, so the air will be humid and moist due to the water in the air going up to make clouds. If you are near a warm air current, you will get more warm ail on top of that. However, if you are closer to a cold air current it will be colder. If you are close to both, you are likely to experience tornadoes and hurricanes due to the warm and cold air currents coming together.
