Answer:
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.
