Unit 1- Ecology Review

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to higher trophic levels.

Front

How much energy is typically available to secondary consumers in an energy pyramid?

Back

Typically, secondary consumers receive about 10% of the energy available to primary consumers, which can be represented as 100 Joules if primary consumers have 1,000 Joules.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction, such as hummingbirds pollinating flowers while feeding on nectar.

Front

What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one species benefits while the other is neither helped nor harmed, like cowbirds feeding on insects disturbed by buffalos.

Front

What is a consumer in an ecological context?

Back

A consumer is an organism that cannot produce its own food and must eat other organisms to obtain energy.

Front

What does a food web represent?

Back

A food web represents all the connections of energy flow throughout all organisms in a habitat, showing how different species are interconnected.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food (e.g., plants), while heterotrophs (consumers) must consume other organisms for energy.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the energy pyramid.

Front

What is parasitism?

Back

Parasitism is a type of symbiotic relationship where one organism benefits at the expense of another, such as a tick feeding on a mammal.

Front

What is predation?

Back

Predation is an interaction where one organism (the predator) hunts and consumes another organism (the prey) for energy.
