The population of rabbits would decrease because the fox and the owl will not have mice to feed on so they will have to eat more rabbits!

Why is it tertiary it makes no sense because it is the second consumer in the food chain this is so frustrating im done forget this i dont need science this is stupid im dropping out just kidding

This type of question can be answered very quickly when you have an understanding of what food chain means. A food chain can be defined as the feeding relationship in which there is a linear network of links in a food web which starts from the producer to the consumers and finally the decomposers. A food chain starts mostly with plants, and they are majorly the producers of the food. They depend mostly on the sun during photosynthesis. The consumers depend on the producers for food.

The decomposers also feed on the consumers, and that is how the cycle continues. From this question, the part that is affected by the sun is the phytoplankton, because it is the producer and producers need sunlight during photosynthesis. The primary consumer here is the zooplankton because it feeds directly on the producer, the secondary consumer is the salmon, and follow by the puffin. So the food chain is; phytoplankton-zooplankton-salmon-puffin

The correct answer to this question is C, Parasitism. This relationship is one between species. In parasitism, one organism, known as the parasite, lives on another, which is the host. The parasite is normally smaller than the host and causes the host harm, while using the host resources to benefit themselves.

Examples of parasites include lice, bats, and fungi. They have been around since ancient Rome and Greece, with the existance of tapeworms and roundworms. It is dated to be first observed by Antonie van Leeuwenhoek in 1681. There are various strategies of parasites including transmitted by contact, by being eating, parasitic castration, and micropredation.

The answer to this is C. The availability of space decreases as feeding levels increase. The number of organisms available in the pyramid usually decrease for each level. There is also more food that are available at the lower trophic levels. If there would not be enough food in the lower trophic levels then the higher trophic levels will not get enough food as well. This can become a problem in the long run.

Remember that only the energy stored in the tissues is transferred from the organism that is consumed from the lower trophic level. If there is one species that would stop existing, there are other species in the food pyramid that will be gone after some time too. Species need certain species in order to survive.

In biology, there are animals that have different relationships with each other. Parasitism is when an organism lives off of another animal in order to survive. They most likely get their nutrients and food from this organism. One example of this is a leech.

A leech may live on an animal in order to suck its blood because leeches live off of blood. Another example of parasitism is when lichen attaches itself to trees. It takes the nutrients from the trees, but this causes the trees to die down.

However, the lichen must be attached to a tree in order to survive. The problem with this is that usually the other organism doesn’t like this organism attaching itself to them because it causes them problems.
