Karen is NOT correct. This is because the sun's energy is a renewable resource. This means that its use is sustainable hence it is a substance of economic value that can be replaced or replenished in the same or less amount of time as it takes to draw the supply down.

Answer:
The five types of interactions between species are
1) Competition: In such a type of interaction, organisms interact by competing for resources such as water, food resources, shelter etc.
2) Predation: In such a type of interaction, organisms of a species known as predators feed on organisms of the other species known as prey. For example, a lion feeding on a deer.
3) Commensalism: In such a type of interaction, an organism of a species benefits from the other organisms and the other organisms neither gains benefit nor loss. For example, Tree frogs using plants for protecting themselves from predators.
4) Mutualism: In this type of interaction, both the organisms of different species gain benefit from each other. For example, insects carry pollen when they move from one plant to another and in turn they use plant as a source of food.
5) Parasitism: It is a type of interaction in which one organism benefits whereas the other one is harmed. For example, Malaria is caused by anopheles mosquito feeding on the blood of humans.
