DEFINITION: study of organisms and the environment: the study of the relationships between living organisms and their interactions with their natural or developed environment

Ecology is the study of the environment and the organisms in it. It also is the study of how organisms work together. -Markie Buettner

Ocean- Individual Population

This is a picture of a turtle in its habitat. He lives in the water where he can hold his breath for very long. He also gets his food here or on land.

Individual- Anything alone or by itself who survives on its on.

Population- Anything in a place or region that live in that area. They all  are the same species and might work together. Individuals make up a population.

Turtles interact with each other by head bobbing to their mate. They interact with the environment by eating kelp and fish. A sea turtle is a truly amazing reptile with many different adaptations. One of its adaptations is its hard shell. The shell protects a sea turtle like a shield from many predators. Another response to the environment is its flippers. The flippers help it swim and dig in the sand.

Ocean Community & Ecosystem

At least 2 species of organisms interacting makes up a community.

Commensalism- interactions between two different organisms: the relationship between organisms of two different species in which one gets food or other things from the interaction while the other remains unharmed and unaffected. Ex: Whales and barnacles. The barnacles eat and get protection and the whale does not get affected.

Mutualism- relationship between different species: a relationship between two organisms of different species that benefits both and harms neither. Ex: The pilot fish and the shark. The pilot fish gets a meal and the shark gets clean.

Parasitism- interactions in which one organism lives in an organism and gets stuff. The other organism is harmed in a negative way. Ex: whales and worms. The worms get in the whale and gets food. While the whale dies or gets hurt.

Community-Organisms that are the same species: a group of organisms with same traits.

Ecosystem- A localized group of organisms together with the environment that they inhabit and depend on.

The organisms depend on the abiotic factors and biotic factors in many ways. They depend on the biotic factors by getting food from them, helping each other out with things, and being able to interact with each other. The organisms depend on the abiotic factors by using them to have a shelter and food. Both abiotic and biotic factors are huge for the ecosystem. The living organisms need the biotic factors.

Six Kingdoms

Shark- Animal

Mushroom- Fungi

Euglena- Protista

Sunflower- Plantae

Animal kingdom- All heterotrophs, All Eukaryotic, and are multicellular.

Fungi kingdom- Heterotrophs, can reproduce asexually and sexually, and scientists believe there are a million or so species of fungi. They can be single cellular and multicellular.

Protista Kingdom- All are Eukaryotic, All are heterotrophs, and all reproduce asexually.

Plantae Kingdom- All are Eukaryotic,  All are autotrophs, and can reproduce asexually and sexually.

Food Chain and Food Web

The killer whale is a very intimidating animal. He eats many different fish and they are scared of him. It is a consumer which means he eats things to get energy. Another name for this besides a consumer is  a heterotroph. He wouldn't be an autotroph because he can not make his own food.

Producer- something that produces: somebody or something that produces something. In science this means they make their own food.

Consumer- somebody or something that consumes something: somebody or something that consumes something by eating it, drinking it, or using it up.

Decomposer- An organism, often a bacteria or fungi, that feeds on and breaks down dead plants or animals, making organic nutrients available to the ecosystem.

Abiotic Factors

The abiotic factors in this are the rocks, water, sun, and sand. These are all nonliving things which means.... they can't reproduce, they can't grow or develop, they don't have one or more cells, they don't exchange gases, and they don't need energy.

Organisms depend on these abiotic factors in MANY ways. If the fish in the sea didn't have water they couldn't live because they need to breath. If turtles didn't have sand they wouldn't be able to bury there eggs and keep them safe. Many animals live on the rocks also and if they didn't have that they would have to leave their habitats. Lastly, if they didn't have the sun they couldn't live because they need heat and some plants in the ocean need the sun to make food.
