What is the first source of energy in an ecosystem?
Think about where plants get their energy.
What do we call organisms that produce their own food?
These include plants and some bacteria.
What is the primary source of energy for biological activities on Earth?
Consider where plants obtain their energy.
True or False: Energy flow in an ecosystem is cyclic.
Think about the direction energy travels through the ecosystem.
In a given ecosystem, the primary producers capture 1000 J of solar energy. If each trophic level loses 90% of energy, calculate the energy available to secondary consumers.
Use the percentage to determine the energy retained at each level.
Critically analyze how energy flow models can impact our understanding of ecological conservation efforts.
Consider how energy prediction can guide conservation strategies.
