BSC 1005 Lecture Notes - Lecture 3: Ecosystem Ecology, Biotic Component, Herbivore

Shawnta used several terms in her post that I want to be sure everyone understands. Ecology is studied with a hierarchy, similar to the hierarchy of classification. The lowest level is the individual. A group of individuals of the same species that live in the same area is called a population. All of the different populations that live in the same area make up a community. So far we have only been talking about the living organisms. When you add in the non-living components of an area you have an ecosystem. The living parts of an ecosystem are called the biotic components and the non-living parts are called the abiotic components.
What are some of the abiotic components that affect what can live in an ecosystem?

All of the organisms plus the nonliving components of a defined area is a/n ____.

Abiotic components of an ecosystem include ___.

The physical place where members of a population typically live is termed a __.

The total of all the resources, both biotic and abiotic, a species exploits for its survival, growth, and reproduction is its __.

When two or more species vie for the same limited resource, _____ occurs.

A relationship between different species in which one species lives in or on another is __.

Which of the following obtain energy and carbon by feeding on producers and one another? (choose one) decomposers, consumers, or producers

A type of symbiosis in which both species benefit is __.

Type of symbiosis where one member of the relationship benefits and has no effect on the other

A type of symbiosis in which one member of the relationship benefits and the other is harmed

Which of the following feed on organic wastes? (choose one) decomposers, consumers, or producers
