The Study Of Ecology
By Henry Gage
Ecology is the study of interactions between organisms and their environment.Commensalism,mutualism,and parasitism are all examples of interspecies interactions.That is also a good example of ecology.
Individual & Population
The picture of the falcon is an individual animal.The second picture is of an individual cow in its population.In this example the falcon is individual because he is separate from the rest of his group.With the cow it is an individual in its population because there is a whole group of cows with it.Over the years the falcon has had to adapt to the growing cities.Now they are mostly found on the city skyscrapers in big cities.They adapted to their environmental changes.
Organisms interact in many different ways to make up a community.Sometimes its predator and prey.Other times its interspecies interactions.Commensalism,mutualism,parasitism.
Commensalism- where one organism benefits while the other is not affected.(Ex.Cattle egrets moving with the cow herd to eat the bugs that the cattle disturb from the grass)
Mutualism - where both organisms benefit from the relationship.(Ex.Bees getting nectar from flowers to make honey and the flowers get pollinated)
Parasitism - where one organism benefits while the other is harmfully affected.(Ex.Ticks suck the blood of animals and give them harmful diseases)
A group of organisms living in a certain area together is a community.An ecosystem is a biological community of interacting organisms and their physical environment.Organisms depend a lot on abiotic and biotic factors in their ecosystems.Predators need prey,and the prey needs food aswell.That's where plants come in.Plants can serve as food,a source of oxygen,and a shelter.Water is also very important survival.You would die without it.The sun is also very important.There are a lot more examples, but we have to move on.
Six Kingdom Classification System
The four pictures i have here are of four out of the six kingdoms.The first one is of a euglena which is in the Protista kingdom.Picture two is of a tree which is in the Plantae kingdom.The third picture is of a mushroom which is in the Fungi kingdom.The forth and final picture is of a cat which is in the Animal kingdom.Three characteristics of the Protista kingdom are the way they move,Unicellular or multicellular,and they are eukaryotic.Three for Plantae are eukaryotic,do not move,and they have a cell wall.A few characteristics of Fungi are eukaryotic,heterotrophs,and no cell wall.Three characteristics of an animal are multicellular,ability to move,and they are heterotrophs.
Food Chain and Food Web
To me one of the most important creatures in the ecosystem is the mushroom which is considered a decomposer.This type of organism decomposes the dead bodies.Without these organisms there would be dead bodies everywhere.They are heterotrophs because they can not produce their own food.They don't have chloroplasts like plants do.
Producer-an organism that contains chloroplasts and produces food through the process of photosynthesis(Ex.plants)
Consumer-an organism that eats other organisms or other organic matter(Ex.most animals)
Decomposer- organisms that break down dead and decaying organisms(Ex.mushrooms)
I chose rock,water,and sunlight for my three abiotic factors.These things are abiotic because they are nonliving.Living things need these things to survive.The rock for shelter,the water to drink for survival,and sunlight to see during the day, as well as getting producers the necessary sunlight they need to produce food and grow.Without these things there would be no life.
