Detailed explanation-1: -It’s important to remember that although the ocean produces at least 50% of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration.

Detailed explanation-2: -The bulk of the world’s tropical rainforest occurs in the Amazon Basin in South America.

Detailed explanation-3: -Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.

Detailed explanation-4: -Because tropical rain forests are some of the oldest ecosystems on earth, they are home to a diverse population of plants and animals. In fact, around 50% of the world’s land-dwelling plants and animals can be found here-with new species still being discovered.
