Energy Flow in Ecosystems

Front

What is energy flow in ecosystems?

Back

Energy flow in ecosystems refers to the transfer of energy from one organism to another through food chains and food webs, starting from producers to various levels of consumers.

What is an autotroph?

Back

An autotroph is an organism that produces its own food using sunlight or chemical energy, primarily through photosynthesis or chemosynthesis. Examples include plants and some bacteria.

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food, typically through photosynthesis. Examples include plants like grass and trees.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers. In a food chain, primary consumers are typically herbivores, such as rabbits.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers. These are usually carnivores or omnivores, such as snakes.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, starting from producers to various levels of consumers.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What happens to the population of predators if their prey decreases?

Back

If the population of prey decreases, the population of predators is likely to decrease as well due to a lack of food.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers, thus playing a crucial role in nutrient cycling.

Front

What is the significance of the sun in energy flow?

Back

The sun is the primary source of energy for most ecosystems, providing the energy needed for photosynthesis in producers.
