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.
The most likely answer here is 1 and 4.
