The four types of competition

The four types of competition are intraspecific and interspecific competition, competitive exclusion, and resource petitioning. Intraspecific competition is competition between two of the same species. An example would be two girls fighting over one guy. Interspecific competition is referred to as the competition between two different species. For example, a cat and a dog are fighting over one food bowl. In competitive exclusion, one species is out-competing another. For example, native plants excluded the non-native plants out of its habitat. Resource petitioning is a species changing over time to reduce competition. An example would be birds, primates, and bats eating a wide variety of fruits instead of just the ones they usually consume.

The importance of eating lower on the food chain.

Eating lower on the food chain would sustain the balance of the flow. Because the animals at the bottom of the food chain is being consumed, the animals would reproduce more and more. This creates more food for the secondary and tertiary consumers. However, if the top of the food chain is being consumed, there would be a dramatic increase of the producers and primary consumers. This would cause the food chain to be unbalanced.

Why is it weaker animals and plants thrive?

Dinosaurs are already strong and other animals do not threaten them as much. However, weaker animals and plants keep changing over time. As these changes occur, they adapt more to their environment, but they will never become as strong as the dinosaur. Because the secondary and tertiary consumers eat the smaller animals and plants, the smaller animals would have to reproduce more to continue their species and to meet the demand. Therefore, weaker animals and plants tend to thrive.

The most important person in history of environmental science

I think that John James Audobon is the most important. He painted lifelike portraits of birds and other animals in their natural habitats. He demonstrated the beauty of how the animals looked back in the late 17th century. This influenced public interest in preserving the beauty of wildlife.

Endangered species we should save

Tigers are at risk of becoming extinct or threatened. Saving the tiger means saving the entire forest kingdom with all the other animals in it. There is more research to be done on tigers. Did they evolve from cats or did cats evolve from tigers?
