Answer:
A forest ecosystem can support a limited number of bears because bears are the supreme predators of their ecosystem and very few animals can hunt bears so nature by supporting a limited number of bear populations supports a balanced number of population of its prey like insects, fishes, deer.
Another reason for the limited population of bear is that bear occupies the highest trophic level in the ecosystem so according to 10% law of energy transfer, it will get very less energy from its food so it needs to eat more.
Therefore the population of bears is limited because the environment can not meet the energy requirement of many bears so a forest ecosystem can support a limited number of bears.
Answer:
Fossils closer to the surface are younger
Explanation:
In the adults, the growth rate slows with age. The healing mechanism of the different cells if damaged is different than that of the younger ones. If a cartilage is damage in the adults, the chondrocytes which are still surviving secrete more extracellular matrix in order to heal the damaged cartilage. The chondrocytes cells are present in the cartilage, and they function to maintain the cellular matrix of the cartilage.
