Answer:
Please read the explanation section.
Step-by-step explanation:
Req. a)
For all organisms, the essential, necessary item is food. For the growth of any organism, food is vital for them. Whether an organism will get their foods or not, is determined by that ecosystem where it lives. From the knowledge of the food chain, we know that there are many types of consumers in a food chain. Some of them are self-dependent for their food, and some of them are dependent on others for their food. Now, if any organism won't get their food from the food chain, they can't survive and can't grow.
Req. b)
Human is an omnivorous species. This means it can eat all. In the food chain of an ecosystem, it can become the secondary consumer and also can become a tertiary consumer. Even it can be a predator too. As an example, we know that in the ecosystem of forest grasses or plants is the producer, deer is the primary consumer, and the tiger is the secondary consumer. Now, a human can eat the dear, and along with this, it can hurt or kill the tiger. This means, a human can be a secondary consumer here and can also be a predator.
Through this type of human activity, competition happens in a food chain. As a result, an organism might don't get their food, and as a result, they can't survive and can't grow.
Req. c)
If the human doesn't become the predator in any food chain and help to maintain the food chain properly, the organism will get the chance to grow up properly. It won't make any negative impact on other organisms. For this, humans have to need to follow some steps. Those are:
- They need to avoid becoming a predator in a food chain.
- They should be kept their role in the food chain.
- They should give a chance to other organisms so that they can get their foods for growth properly.
- They should not kill or hunt any primary consumer or secondary consumer.
