3a)i An ecosystem is a community of plants and animals interacting with each other in a given area, and also with their non-living environments. The non-living environments include weather, earth, sun, soil, climate and atmosphere. The ecosystem relates to the way that all these different organisms live in close proximity to each other and how they interact with each other. For instance, in an ecosystem where there are both rabbits and foxes, these two creatures are in a relationship where the fox eats the rabbit in order to survive. This relationship has a knock on effect with the other creatures and plants that live in the same or similar areas. For instance, the more rabbits that foxes eat, the more the plants may start to thrive because there are fewer rabbits to eat them.

Ecosystem is a system that includes all living organisms (biotic factors) in an area as well as its physical environment (abiotic factors) functioning together as a unit.

In a simple ecosystem that consists of rabbits and grass. The grass reproduces at a certain rate, and the rabbits randomly wander around the world eating the grass. If a rabbit stumbles across a patch of grass, they will eat it and gain energy. If a rabbit gains enough energy, they will reproduce. Conversely, if a rabbit wanders around too long without finding any grass to eat, they will die.
