Ecology
Ecology is study of ecosystems and how species interact with each other and the environment. There are many different levels of organization in ecology. As for location, the biosphere is largest. Biosphere means all of the ecosystems on earth, and within that is biomes. Biomes are determined by their climate. Some examples of biomes are tundras, Taigas, Temperate, Deserts, Savannas, and Tropical Rainforests. Within biomes are ecosystems. Ecosystems are the biotic and abiotic factors of an environment like the water, rocks, trees, and so on. After ecosystems, comes habitats. A habitat is where a certain species is inhabited. Within habitats are niches. Niches are the organism's role in their environment.
In organisms, there are different levels of organization. Organisms are any living thing. Within organisms, comes communities. Communities species that interact with each other in a certain environment. After communities is population. Population is the number of organisms, classifies as a species who live in the same environment. Within population is species. Species are organisms that are able to interbreeding and exchange genes.
There are many reasons why there is a variety of ecosystems. All species have different requirements they need in order to survive. Their ecosystem must support these requirements, otherwise, the species will die out. Also, ecosystems are based off of energy. The tropic levels in an ecosystem pass on ten percent of energy to each following level. Cuttlefish are secondary consumers.

Another reason why ecosystems come in a variety is because of competition. Competition is a negative relationship between organisms that occurs when there is a lack of resources. If there are not enough resources for each species,or even organism, there would be a lot of competition.
Symbiosis is the long term interaction between two organisms. There are three specific symbiosis relationships. The first one is mutualism, which consists of two organisms interacting with each other, both benefiting from these interactions. The most common example of mutualism is a bee and flower relationship, as the bee gets nectar, the flower becomes pollinated. The second relationship is commensalism. Commensalism is when two species interact with each other with one benefiting from this, and the other not affected. An example of this would be a mollusk and barnacle relationship, because the barnacles are able to obtain nutrients without harming the other organism. The last symbiotic relationship is parasitism. Parasitism is the relationship between two organisms in which one benefits becoming detrimental to the other. Leeches and humans would be an example of this because, the leech benefits from the human's blood, while the human is loosing blood.
Cuttlefish prefer to live in shallow reefs, near the coast all around the world. Cuttlefish eat shrimp, crabs, and fish, and that interaction would be a predator prey relationship.
