1-what are three ways organisms deal with limited resources

2-How do organism interactions ensure that energy flows through an ecosystem

1-there are three types of short-term and long-term relationships between organisms: parasitism,

mutualism and commensalism

2-through producers, consumers and decomposers

Explanation:

1 - Mutualism is a relationship in which both species benefit.

Commensalism is a relationship in which one species benefits and the other species is not

affected.

Parasitism is a relationship in which one species benefits while the other species is damaged.

2-Producers: autotrophic organisms, examples, plants, algae and bacteria. They make their own

organic matter from inorganic matter.

- Consumers: heterotrophic organisms that feed on living organic matter, examples, herbivores,

carnivores and omnivores: they feed on both plants and animals.

-Decomposers: heterotrophic organisms that feed on debris and convert them into inorganic

compounds, examples, fungi and bacteria.

1 - Animals survive when they compete. In limited resources, animals either compete, kill or co-operat. There are 3 ways animals complete with each other to get access o limited resources. These ways are:

- Parasitism - In this relationship, one animal gets benefit and the other gets hurt.

- Mutualism - in this interaction, both organisms benefits each other and survives.

- Commensalism - In this interaction, one organism gets benefit whereas the other gets nothing in return.

2 - Living organisms are classified as:

- Producers

- Consumers

- Decomposers

Producers are the energy generators. They are the biggest source of energy for other levels. Consumers feed on producers and other animals. And the end, when consumers die, decomposers feed on them, break down their bodies and mix it with soil increase its fertility and the cycle of energy flow goes on.
