Why are there more mice than lions in an african ecosystem?
r-ruslan [8.4K]
I would think on of the reasons is because the food that mice eat has a greater variety, in the sense that while a lion may only eat meat and have to catch its prey the mice can eat without relying on other animals. Lions also have more competition between other animals like them for example cheetahs and leopards on the other hand a mice is more independent. On period where food is scarse mice can get on with eating what the earth provides like plants lions can’t.

Explain any two specific adaptation that allow animal to survive in Mountain habitat<br><br>​
IRISSAK [1]

Answer:

Among others, two adaptations might be

  1. Avoiding corporal heat loss
  2. Increasing oxygen absorption  

Explanation:

Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:

  • Avoiding heat loss. Temperature tends to be very low at highs, so, to <u>avoid heat loss,</u> animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate.
  • Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown.
  • Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements.
  • Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
