Energy enters a food chain as heat energy and leaves it as light energy.
hjlf

Answer:

The statement that says "Energy enters a food chain as heat energy and leaves it as light energy" is false.

Explanation:

The energy that enters the food chains, first of all, is light energy from the sun. This energy is assimilated by plants to convert it into chemical energy, through  photosynthesis.

When energy flows from producers, plants, to consumers and decomposers, a great amount of <u>energy is lost, in the form of </u><u>heat energy</u>, due to the metabolism of living beings. Additionally, the second law of thermodynamics states that when energy passes from one form to another it leads to disorder in the system, which would also explain the loss of energy.

The true statement is "Energy enters a food chain as <u>light energy</u> and leaves it as <u>heath energy"</u>.

Read the Mungo Lady and Mungo Man Do others in the field of anthropology agree with Dr. Thorne's view? Explain.
sweet [91]
I've read the story back a couple months ago

Actually, there are many archeologists and anthropologists disagree with dr. Thorne's view. Basically, Thorne strongly believes that what many calls Homo erectus was, in fact, Homo sapiens, and that they migrated out of Africa almost 2 million years ago and dispersed throughout Europe and Asia. That would actually be very different from what scientists have always believed about the evolution of the species. That is why many of them are against him)

I hope I helped :)

Does a sunbird benefit the plant from which it drinks nectar?
Airida [17]
I believe the sunbird would benefit the plant because it would pollinate them. Going from flower to flower, pollen would get stuck on it's feathers and it would pollinate other flowers, like a bee.
