Biology Webquest Review: Ecology (Tasks 27,28,29)

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the amount of energy available at each trophic level.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, use sunlight to make food through photosynthesis, forming the base of the food web.

Front

What are decomposers?

Back

Decomposers are organisms, like bacteria and fungi, that break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What percentage of energy is typically lost at each trophic level in an energy pyramid?

Back

Typically, 90% of energy is lost at each trophic level as heat or used for survival.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which energy and nutrients flow, while a food web is a more complex interconnection of multiple food chains.

Front

What are apex predators?

Back

Apex predators are animals at the top of the food chain with no natural predators, such as hawks and lions.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity enhances ecosystem resilience, productivity, and stability, allowing it to better withstand environmental changes.

Front

How do toxins accumulate in food chains?

Back

Toxins can accumulate in food chains through a process called biomagnification, where higher trophic levels consume more contaminated organisms.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or web, defined by how an organism obtains energy (e.g., producers, primary consumers, secondary consumers).
