Choose all the answers that apply. energy in an ecosystem: flows only one way is part of an open system is recycled and reused is eventually lost as heat is transferred through the food chain

The correct answers would be:

In contrast to nutrient, energy flow only in one direction only in an ecosystem.

In an ecosystem, the energy is transferred through food chain. The producers convert solar into chemical energy. 10 percent of available energy is then transferred to the next trophic level (herbivores) and rest of the energy is lost as heat.

Similarly, the energy is passed on to secondary and tertiary trophic levels.

Ultimately, the energy is lost as heat released during decomposition.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

a. by using fur or clothes to trap heat energy near the body
