Answer:
4. if if it can outcompete native species or If the species has evolved under great competition or predation
5. area of habitat connecting wildlife populations separated by human activities or structures
6. Habitat corridors allow movement between isolated populations, promoting increased genetic diversity, they also provide food and shelter for a variety of wildlife
7. Because of the trophic pyramid
8. the change in the frequency of an existing gene variant in a population
9. Models for biologists, geneticists and ecologists to understand extinctions
10. Mutualism is the interaction between two or more organisms where both organisms can benefit from the interaction and Commensalism is when two species interact, however only one benefits but the other is not harmed.
11. the first one is producer
the second one is a Primary Consumer
the third one is a secondary consumer (there are actually four so I will put that as well)
the fourth one is a Tertiary Consumer
13. An endangered species is a species that is very likely to become extinct in the near future
14. An invasive species is a species that negatively impact their environment for example, a lionfish
15. the THREE (I think your paper is mixed up a bit btw) types of biodiversity are Genetic diversity, species diversity, and ecological diversity
16. I am unsure of this one, sorry!
17. a keystone species is is a species that if they were removed from their ecosystem it would make a huge difference - the reason this is so important is because, a keystone species is an organism that helps define an entire ecosystem
Indicator species are organisms that can tell us about the levels of pollution in an area by their presence or absence- they are important to scientists because, they indicate the water quality of an ecosystem.
18. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene
19. No other species would be able to fill its ecological niche, the ecosystem would be forced to change
Explanation:
Sorry this took so long
also, I learned about all of this last year in Biology in my Freshman year of high school, good luck!
