Food Webs + Energy Pyramids

Front

What is the primary source of energy in a food web?

Back

The primary source of energy in a food web is sunlight, which is captured by producers such as algae, plankton, and seagrass.

Front

What is another term for producers in an ecosystem?

Front

What are the different trophic levels in a food web?

Back

The main trophic levels are producers (first level), primary consumers (second level), secondary consumers (third level), and tertiary consumers (fourth level).

Front

Back

The green trophic level typically contains secondary consumers.

Front

What is an example of a producer in an ecosystem?

Back

Grass is an example of a producer.

Front

What does a food pyramid represent?

Back

A food pyramid represents the relative amount of energy available at each trophic level in an ecosystem.

Front

What is the role of autotrophs in a food web?

Back

Autotrophs, or producers, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

How does energy flow through a food web?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and so on, with energy decreasing at each trophic level.

Front

What is the significance of the green trophic level?

Back

The green trophic level signifies the presence of secondary consumers, which feed on primary consumers.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers eat producers (herbivores), while secondary consumers eat primary consumers (carnivores or omnivores).
