Ecosystems Explanation Writing

Since the past term, Te Ngahere have been working on an explanation about ecosystems. We were learning to use the correct structure for an explanation. I enjoyed learning about ecosystems and what they need to have in them. This explanation is better than any of my other explanation writings.

What an Ecosystem needs?

Living in all ecosystems are inorganic matter and organic matter. Inorganic matter is a non living thing but is very important in an ecosystem. Organic Matter is a living thing. Producers and consumers are organic matter because they are all living things. All ecosystems need these to become a healthy ecosystem.

Inorganic Matter

Inorganic matter is a big part of the ecosystem even though it’s not alive. There are many different types of inorganic matter such as rain, grass, rocks, sand and much more. All these things help producers and consumers to stay alive. For example grass helps consumers because they produce food for them to eat.

Producers

Producers are plants that can produce energy on it’s own. Like trees, seaweed and kelp they create energy from sunlight. Without producers food chains would be unbalanced. They also produce energy for consumers because consumers can’t produce food for themselves. For example, kelp produce energy from sunlight then consumers come along and eat the producers to take the energy from them.

Consumers

Consumers are a big part of the ecosystem. Some consumers feed off producers which means they are herbivores. Other consumers eat each other to stay alive and survive and they are called carnivores.

Decomposers

Decomposers are a bit different to the other living things. A decomposer is a nonliving thing. They break down dead matter with chemicals inside of them. Example worms are decomposers. They recycle the dead matter into chemicals which they release into the air and water. This is very important because without decomposers recycling the dead matter and releasing chemicals into the air plants won't be able to get nutrients that they need.

Ecosystems are very fragile. When you damage one part of the ecosystem you affect the whole area. The food chain will become unbalanced and it won't be good. For example at Matai Bay there is no kelp because people were overfishing and taking to much snapper and crayfish so there were to many kina eating all the kelp. Ecosystems are very fragile and us kaitiaki need to protect our environments.
