Unit 8 Ecology

Regulate body temperature internally

Regulate body temperature externally

Positions in a chain showing energy transfer

Produce own food through photosynthesis

Rely on other organisms for food

Births minus deaths plus net migration

Growth rate multiplied by population size

Growth rate reduced by carrying capacity

Interacting populations in a specific area

Quantifies species diversity in a community

Interaction between predator and prey populations

Impact of predator on lower trophic levels

Species divide resources to reduce competition

Higher diversity leads to ecosystem stability

Critical species maintaining ecosystem balance

Increase diversity through genetic variation

Threats include habitat destruction and pollution

Introduced species disrupting ecosystems

Natural disasters altering ecosystems

Diverse ecosystems recover better from disturbances

Maintain balance and diversity in ecosystems

Ecosystem deteriorates

Enhance genetic diversity in populations

Populations grow rapidly without resource constraints

the variety of plant and animal life in a habitat

Major ecologica community with distinct climate and flora

And animal that feeds chiefly on grass and other plants

A terrestrial or aquatic flesh-eating mammal

An animal that feeds on both animal and vegetable substances

study of the relations of organisms to their environment

Organisms interacting with their physical environment

break down

an animal or plant that lives in or on a host

the relation between two organisms that benefit each other

when one organism benefits from another without damaging it

the area in which something exists or lives

an organism who takes in sunlight and converts it into a chemical sugar
