Describe a reason that ecosystem stability is important to the life forms in the ecosystem, and then describe why stability in one ecosystem is important for stability in an adjoining one

Answers

Different life forms adapt to their environment. Stable ecosystem creates a stable environment for life forms. In stable environment, life forms do not have to adapt all the time and their energy can be invested into other life processes, such as growth, reproduction, etc. Stability of ecosystem is important for adjoining ecosystems because that way boundaries and influences could be extended. Stable ecosystems are able to interact and both benefit from each other.

Answer:

A. In a stable ecosystem, life forms have enough food for energy and they are not wasting that energy trying to adapt t their environment. This gives them added opportunities to grow and reproduce. A stable ecosystem can extend its boundaries and interact with an adjoining ecosystem which could benefit both ecosystems.

Most aquatic animals conduct _____ fertilization.

Answers

external would be the answer!

Answer:

The correct answer is "external".

Explanation:

External fertilization is a type of sexual reproduction where the fertilization takes place outside the body of the female organism. This type of reproduction has the advantage that the mother does not need to carry the embryo while it develops. External fertilization is particularly common in aquatic animals, where only sharks and a few types of fish do not reproduce using this adaptation.

Answers

The answer is competition.


Competition is an interaction between members of the same species or between different species. If resources, such as food, water, sunlight, territory, are limited and several species depend on these resources, then, they must compete with other species to gain the resources. In this example, bears and coyotes depend on deer and when deer population is reduced, bears and coyotes must compete in order to survive.

Answer:

Its competition

Explanation:

Bears and coyotes will fight over the deer if the deer are in short supply so they won't have much deer to consume

There were equal amounts of all four bases in every organism, or 25 percent of each base.
