Producers,Consumers, and Decomposers

What are producers, consumers, and decomposers? These three terms indicate how an organism gets its energy and interacts with the other living things in its community. Producers are organisms that use a source of energy to make their own food. However, consumers are organisms that cannot make their own food. Therefore, they feed directly or indirectly on producers and depend on them for food and energy. In this category, there are three types of consumers. The three kinds are herbivores, carnivores, and omnivores. While herbivores only eat plants and leaves, carnivores only eat meat. However, the kind that eats both plants and meat is called an omnivore. Humans for example, are omnivores. Deers are herbivores and lions are carnivores. Besides producers and consumers, we also have decomposers in our ecosystem. Decomposers are organisms that break down dead matter into simpler substances. Bacteria and mold are two examples of decomposers. Also, along with breaking down dead matter, decomposers also start and end every food chain. In conclusion, producers, consumers, and decomposers are three terms that tell how different organisms obtain energy and interact with other living things in their community.

Enviornment and Habitat

What is your environment? First of all, environment is where an organism lives and obtains the needs for its survival. Your habitat also provides you with resources that you need to live in the given area. In a certain environment, there could a community or a population. Community is where all the different organisms live together in a given area where in a population, the same species, or same types of organisms live together. Aside from this, not many organisms can adapt to new habitats whereas humans can. An example of this would be that if an architect was to design a new home for the cheetahs in a zoo, then he would have to now the environment the cheetahs live in. Since the cheetahs cannot adapt to a new habitat, the architect would have to design a home with the resources found in their natural environment. After learning about environments and different habitats I am really interested in learning more. This topic was very pleasing and I hope to learn more about it.
