3.1.1. Why does life thrive in the tropical rainforest? The tropical rainforest is very rich in water and food thus life thrives. We all know that food and water are the things that animals need the most for their survival. It also has a warm temperature due to the constant energy that the sun provides. The plants need the sunlight for the process of photosynthesis to be completed and use it to derived energy. And the plants serve as the food for some animals and these animals serve as the food

An example would be that it could serve as a shelter to an animal (commensalism). Trees also give us oxygen essential for life. This makes us realize how important trees are to our society. To imagine that trees are the longest living organisms known to man shows the significance of having trees in our presence. In conclusion

The Selfish Gene Author: Richard Dawkins Book Criticism •“Genes cannot be selfish or unselfish‚ any more than atoms can be jealous‚ elephants abstract or biscuits teleological. This should not need mentioning‚ but Richard Dawkins’s book The Selfish Gene has succeeded in confusing a number of people about it” (Midgley). •There are many things to disagree with in the book‚ depending on one’s viewpoint. Some people may interpret the term “selfish gene” in a literal way‚ believing that

Each interaction depends on the one before it. Commensalism - Barnacles and whales Barnacles are arthropods contained in the class Crustacea along with lobster’s crabs and shrimp. They’re believed to be one of the oldest surviving animals on Earth. There are more than 1‚000 species of barnacles inhabiting
