Answer:
The cardio-respiratory system works together to get oxygen to the working muscles and remove carbon dioxide from the body. During exercise the muscles need more oxygen in order to contract and they produce more carbon dioxide as a waste product.
Explanation:
They are the energy needed to do all everyday things
The forearm of birds, reptiles, and humans illustrates a homologous body structure.
- Similar physical characteristics found in species with a shared origin are known as homologous structures, although these characteristics have entirely different biological purposes.
- The limbs of humans, cats, whales, and bats are examples of homologous structures.
- All of these structures—arm, leg, flipper, and wing—are supported by the same type of bone structure.
- The arms of a person and the wings of a bat are excellent examples of homologous structures. Because both bats and people are mammals, they have a common ancestor.
- Even though they appear considerably different from one another from the outside, a bat's wing and a human arm have remarkably comparable internal bone structures.
- Wings help bats fly, whereas arms enable human interaction with their environment. The wing and the arm also have various purposes.

Answer:
The correct answer is C) benthic ocean
Explanation:
Sun is the ultimate source of energy for almost all the organisms present on the earth. The organism that especially lives on land are highly dependent on solar energy because all the plants and most algae require sunlight to make their food and they are the primary produces on which other organism are dependent.
Benthic ecosystem are the ecosystem that is present at the very depth of the ocean or on the ocean floor. So in that much depth, there is very little or no penetration of sunlight occurs. So the ecosystem there does not directly depend on sunlight for there survival. So they benthic ocean ecosystem would likely survive the longest.
