What is ecology?
Ecology is the study of abiotic factors and biotic factors working together. Abiotic meaning non-living and biotic meaning living. Scientists work to study interactions between other species and how they interact with the surrounding environments. Scientists also look at biomes. Biomes are defined by climate and make up the biosphere. There are six biomes on Earth today: Tundra (cold & dry) Taiga (cold & wet), Tropical Rainforest (warm & wet) , Temperate Forest (cold & hot) Desert (hot and dry) and Savanna (moist & dry). These are biomes because they're defined by their climate.
Why are there a varity of biomes?
This all comes down to where the place to according to the equator. Places such as the Savannas and Deserts have dry climates. This is because warm air is being pushed from the equator to create the dryness. Tropical Rainforests have moist and hot weather because they're near the equator and are being rained on constantly. Temperate Forests are both cold and dry because they get both dry air rising as well as moist cool air. Lastly, Taigas have cold and moist weather because of the cold winds with the poles combined with water evaporation.
Competition is an interaction between organisms. There are two types of competition; Intraspecific and interspecific. Intraspecific is between organisms in the same species whereas interspecific is between organisms of two different species. There are also things called niches. These are the role a certain organism has in an ecosystem. Niches however, prevent competition because if each organism has its own role, there is no one to compete with for the same role. There is also an interaction known as predator and prey. The predator is the organism eating the prey.
Symbiosis and the three types:
1) Mutualism-- Both organsims benefit. For example, pollination. The bee receives food and the flower gets pollinated
2) Commensalism-- One organism benefits and the other is unaffected. For example, a bird in a tree. The bird gets a place to live and the tree is unaffected.
3) Parasitism-- One organism benefits and the other is harmed. For example, when a mosquito bites a human, the bug gets a tasty meal and the human gets a itchy bite or at worst malaria.
The angler fish role in an ecosystem
The Angler Fish lives deep deep down in the ocean. They obviously can only live in aquatic biomes, yet they prefer dark ones. Therefore it is very hard to make "friends" with other species. The only kind of interaction is intraspecific. The male fish attaches to the female fish to feed of its nutrients and the female has sperm whenever she is ready to reproduce. Anglers tend to eat small fish, but when food is scarce, they unhinge their jaw to eat fish up to twice their size.
The Angler Fish is a Tertiary Consumer, or Carnivore. This means it is at the top of the food pyramid. It eats other fish and has no predators. At the bottom of the pyramid are producers that make their own food. Next is Primary Consumers, or herbivores, that eat the Producers. Then comes Secondary Consumers, or omnivores that eat the Primary Consumers. And lastly come the Tertiary consumers.
