Question

The ENDANGERED ANIMAL is CA least tern and its a bird 

1. Species Description Visual description, size, reproduction, lifespan, unique behaviors

2. Habitat Needs & Ecological Roles What type of habitat does it require? What does it eat? Who eats it? What role does this species play in its biological community?, etc.

3. Geographic Range/ Population Status Where is this species found geographically? How does its current range compare with where it’s distributed today? How many of these organisms are present in our region? (Or – if you can’t find overall numbers, is there data available on specific populations of this plant/animal?)

4. Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story.

5. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.)

6. Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?

Expert Solution
Step 1

Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.

The change in the heritable characteristics of the species across many generations is called evolution. Evolution is a gradual process, and according to the theory of evolution, all species are related and evolved gradually. According to the theory of evolution, all living organism on the earth has a common ancestor.

The species problem is the group of inquiries that occurs when evolutionary biologists try to define the term species. The definition that describes what a species is, termed species concept.

Ecology is the study of the associations among living organisms and their physical environment.
