Answer:
Producers are responsible for providing energy to the rest of the ecosystem.
Explanation:
Producers are literally the basis of all food chains, if they do not exist, it is impossible for energy to pass from one trophic level to the next.
Producers are represented by plants that, through photosynthesis, produce enough energy to be passed to all living organisms, through the food chain. For this reason, it is important to maintain the stability of the producing population, since the stability of the entire ecosystem depends on it, since it is through it that energy is provided for the rest of the ecosystem.
d. an opening specified for waste removal is present
Bears remove undigested food through an opening designated for waste removal, also known as the anus. This is characteristic of an alimentary canal system where food enters orally and waste leaves through a separate exit. This type of digestive system is referred to as monogastric.
In the case of bears, and other animals with a similar monogastric digestive system, the undigested food is excreted via an opening designated for waste removal as suggested in option D. The process begins in the mouth where food is broken into small particles. This food then travels to the stomach where digestion continues with the breakdown of large molecules. The digested nutrients are then absorbed into the body in the intestines. Any undigested food that is not absorbed is removed as feces through an opening known as the anus. This type of digestive system is also known as an alimentary canal, which is a complete system with an oral intake and a separate waste removal opening.
