The Easter Island once used to be extremely diverse in biodiversity. It had abundant amount of plant and animal species living there.
Biodiversity in the past was extremely high due to favorable conditions there. The temperature and climate of Island was favorable for the growth of plants and animals.
It has mild climate with fertile soil which favored growth but now the scenario is different as it is now barren land with lots of sand and no diversity among plants and animal species is found there.
They are directly related. The more different trees, the more different birds because not all birds like the same trees:
Some like higher trees to build higher nests, others like lower trees, some like the leaves of some trees useful, some live in the trees that give them fruits, other in trees where many insects go, etc.
Hope it helped!
cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.
Explanation:
The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.
The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
"The liver produces bile which emulsifies fats i.e. breaks them down into small droplets for a larger surface area. This will increase the rate at which the fat is digested by lipase. Bile also neutralizes the acid produced by the stomach to provide ideal alkaline conditions for enzymes in the small intestine."
