The correct answer is - predator species in a community.
In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.
The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.
If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.

One of the main functions lipids do is storing energy. If a person eats excessive amount of food, lipids help store the energy in the form of fat molecules in the body to use later.
Hope this helps!
The sun provides the energy just like it provides energy for most things on this planet.

If you were to just dump 10 million liters of crude oil into a lake without knowing what it would do... If the results were bad, then that would harm the environment. (And I guess we all know what will happen if oil is dumped into a lake.)
