what are the 5 types of marine ecosystems and where is each type found
15.1 -1how does the meaning of the word ecology relate to this branch of science?
ecology means home or houses so ecology is the study of home of animals. it is the study of how animals interact in community. understand and describe the relationships among living things.

15.1 if you described your school as an ecosystem at what level of ecology would you place yourself?
biotic factor
a living part of an ecosystem
abiotic factor
a nonliving part of an ecosystem
John Ray
English naturalist; defined the terms Genus and species. Genus: a group of closely related organisms. Species: a group of organisms that are structurally similar and can pass these similarities on to their off-spring (capable of mating or breeding to produce fertile offspring).

a relationship between two organisms in which one organism benefits and the other is unaffected
the struggle between organisms to survive in a habitat with limited resources
relationship in which one organism inhibits another
interaction in which one animal (the herbivore) feeds on producers (such as plants)
15.5-1 Why do ecologists classify biomes according to plant life rather than animal life?
15.5-2 what are some abiotoc factors that influence the development of different climax vegetation in different biomes?
