Ecosystem: Components, Interactions and Energy Flow

A simple way to look at the transfer of food energy through an ecosystem in an ecosystem is

• through a trophic level

• through a Food Chain

• through a Food Web

Herbivores eat

• Everything

• only plants.

• only meat

Decomposer is responsible for

• eating all the meat.

• recycle nutrients in an ecosystem.

• eat only plants.

Trophic Levels represent ...

• level of students at VOHS.

• levels of nourishment in a food chain.

• level of largest plants

Models the complex network of feeding relationships

• trophic levels

• food webs

• food chains

Plants are...

• producers

• herbivores

• omnivores

Calories, kilocalories, and joules are a measure of

• species

• energy

• plants

Ecosystem

• The thin layer of land, air, and water that is home to all living organisms

• Consists of all the living organisms and their interactions with

  nonliving components.

• All the members of the same species living in one place.

• The flow of energy patterns involving the feeding relationships between producers and consumers in a community.

Biodiversity

• The flow of energy patterns involving the feeding relationships

  between producers and consumers in a community

• The total number of animal and plant species in an ecosystem.

• The living components of an ecosystem.

• The nonliving, physical factors that affect the living components in an

  ecosystem.

Biotic

• The flow of energy patterns involving the feeding relationships

  between producers and consumers in a community

• The total number of animal and plant species in an ecosystem.

• The living components of an ecosystem.

• The nonliving, physical factors that affect the living components in an

  ecosystem.
