Protecting different kinds of wildlife.Restoring vegetation in certain areas.Ensuring improvement of environmental health.Relocating ecosystems away from polluted areas.

Explanation:

These are all the factors that are included in watershed conservation. Watershed conservation is very important to the environment for several reasons. Freshwater from the watershed is often used by people for the purposes of drinking, cleaning and bathing. Conserving this source allows us to avoid the depletion of freshwater supply. Moreover, it is important to ensure that such water is not polluted, both for the benefit of humans, as well as to ensure that plants and animals that require this water are able to access it safely.

Answers

I am pretty sure that the answer is D.) 50%

Answer:

Explanation:

So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.

Hello. This question is incomplete. You forgot to put the diagram and answer options.

The diagram is in the figure attached below and the answer options are:

Where the tertiary consumers get their energy

How often primary producers are able to reproduce

When bacteria and fungi initiate the process of decomposition

 Whether other secondary consumers are present

Answer:

Where the tertiary consumers get their energy

Explanation:

The diagram establishes the visualization of a food network where it is possible to visualize all the relationships between predators and game, in addition to being possible to observe the relationships between each trophy within a food chain.

With this, it is possible to determine all the ways that tertiary consumers are able to obtain energy and observe how that energy reached them.

B)

and fox
The niche filled by the owl will be empty. The other animals within the
food web will grow unchecked.
Without the owl present, the empty niche will result in an overpopulation
of hawks. Eventually the lower-level consumers will disappear
DY

Answers

Answer:

I'm pretty sure it is the third option: The niche filled by the owl will be empty. The other animals within the  food web will grow unchecked.

Explanation:

The owl is a predator animal. As it hunts small prey, it keeps the population of those prey animals stable. If the owl is taken out of the habitat, then the population of the prey animals it used to hunt will grow out of control.

The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.

What is a food web?

All the food networks in a single ecosystem make it into a food web. Each organism in an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as they move through the environment. A food web is made up of all the linked and overlapping food systems in an ecosystem.

The trophic levels are divisions into which organisms in food webs are categorized. These levels can be roughly categorized as producers (first trophic level), consumers (second trophic level), and decomposers (final trophic level).

The first trophic level is producers. Producers often referred to as autotrophs, produce all of their own food and do not rely on any other living thing for sustenance. The majority of autotrophs convert sunlight, carbon dioxide, and water into food (a nutrient called glucose) through a process known as photosynthesis.

The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live near active volcanoes make their own food by using sulfur rather than carbon dioxide. Chemosynthesis is the name of this process.

Therefore, The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.

The scientific name of an organism is made up of what two group names?

Answers

Scientific names follow a specific set of rules. Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species.

Answer:

Genus species

Explanation:

Scientists use a special naming system for organisms. It is made up of two words.

The first word is the genus of the organism and the second word is the species of the organism.

The first word, which is the genus, is always capitalized, but the second is not. Both words are italicized if possible, but if you are handwriting the scientific names, an underline suffices.

what would happen if a new predator was introduced into the ecosystem that only ate mice ? Would the mouse population be lowered ?What else would happen because of this

Answers

Answer:

The mice population would be lowered, and that predator could be a prey to other predators in that environment.

Explanation:

The introduction of new predator has both positive as well as negative effects on the ecosystem and environment.

What happen when the predator in introduced in an ecosystem?

If a new predator was introduced into the ecosystem that only ate mice so this results in the reduction of population of mice which leads to the disturbance of the ecosystem.

So we can conclude that introduction of new predator has both positive as well as negative effects on the ecosystem and environment.
