Applied Biology - Chapter 5 "Populations and Communities"

The specific sequence in which organisms obtain energy in an ecosystem.

Symbiotic relationship where one organism benefits and the other neither benefits or suffers harm.

A smaller ecological unit consisting of all the members of a single species that live in the same area and breed.

Trophic level where organisms cannot make their own food.

In predation this is the organism doing the killing and feeding. Ex. - Hawk

Organisms that eat both primary producers and consumers. They eat both plants and animals.

Organisms that eat primary producers or "plant eaters".

An organism that eats a primary producer.

Symbiotic relationship in which both organisms benefit from living together.

An organism that eats a primary consumer.

The organism in parasitism that is giving the benefits and being harmed.

When one organism obtains its nutrition from another organism and harms it.

All of the populations in an area.

The way of life of a species.Includes its habitat, feeding habits, reproductive behavior, and all aspects of its Biology

A biological relationship in which two dissimilar organisms live together in close association.

The physical area in which an organism lives.

Organisms that eat other consumers.

Whenever one organism eats another, energy in the form of chemical bonds is transferred from one organism to another.

Consumers can be classified by the type of food that they eat.

Winterfield pond is an example of a community.

A trophic level where organisms can make there own food.

The use or defense of a resource by one organism that reduces the availability of that resource to other organisms.

Autotrophic organisms that manufacture all of the organic nutrients for an ecosystem. Beginning of all food chains.

The feeding level of an organism in its ecosystem.

The organism in predation that is being killed or fed upon. Ex. - Mouse

Competition between organisms of the same species.

When one organism feeds upon another. Ex. - Lion feeds on a gazelle.

List in order from the bottom the 5 basic parts to a food chain.

Organisms that break down dead tissues and wastes into N, C, P, and other elements and compounds. Ex. - Bacteria

Organisms that feed on organisms that have recently died.

The organism is parasitism that is harming the other organism and receiving the benefits.

Competition between organisms of different species.

All of the interrelated food chains in an ecosystem.
