1) biotic is a living component contributing to an ecosystem; so the answer is insects
2) abiotic Is non living; so the the answer is wind.
3) abiotic, remember droughts, Floods etc are non living.
4) population density (I think)
5) Habitat (I think)
6) organism
7) sea horse
8) rock

biotic factor- any living part of an ecosystem ex. tree, bird, etc
abiotic factor- any non living part of an ecosystem ex. rocks, soil, temp, etc
a niche is a special role an organism has in its ecosystem
a population is a number of the same species that live in the same habitat ex. prarie dogs all live on a prarie
a community is many different populations living in the same enviroment ex. animals and plants living in a pond or a lake
