E3 Ecology Flashcards
What is the study of how organisms interact with each other and their environment?
Ecology
What is made up of all the living organisms that inhabit in a particular area?
Community
What is a community of species and the physical environment that it interacts with?
Ecosystem
What is the number, identity, and relative abundance of species in a community?
Community structure
Pathway along which food energy is transferred from one trophic level to the next.
Food chain
What is how many times the chemical energy in food has passed from “eaten” to
eater?
trophic level
What percent of biomass in one trophic level gets incorporated into the biomass of the next
trophic level?
10%
Diversity of a community is made up of two factors:
- Species richness
- Relative abundance
The number of species present is called
species richness
what proportion of the community each species make up
Relative abundance
