There are thousands of specific ecosystems on Earth, such as rainforests, wetlands,
deserts, forests, rivers, lakes, grasslands...

答案
Task 1 There are thousands of specific ecosystems on Earth, such as rainforests, wetlands, deserts, forests, rivers, lakes, grasslands...
Task 3 One possible version:
Introduction Today we're going to talk about the desert, an ecosystem that is dangerous but important to us all.
Body (1) Location: You can find this ecosystem in Africa, Asia, America and Oceania (大洋洲). (2)Feature: Deserts are usually known for being very hot, dry, and hard to live in. However, desert animals like camels live peacefully with humans. People can also benefit from the oil under parts of the desert. (3)Problem: But because of the rapid development of tourism, pollution is a big problem for this ecosystem. Mining, cars and factories bring waste and dust, which harms desert animals and plants. (4)Solution: Luckily, many local governments are trying to get tourists to come while also protecting the environment. All waste is carefully collected and dealt with in the town. And an important point that needs to be kept in mind is that not all deserts should be turned into green fields. We need to be more cautious about this problem.
Conclusion As people are paying more and more attention to environmental problems, one day everyone will understand that it's important to let nature have her way.
