Low Oxygen Level
- Definition: The largest number of indivisuals of one species that an enviroment can support.
- Resources Needed For Population To Survive: Food, Shelter, Water, and Space
Populations will constantly change over time depending on changes in the habitat. In an ocean, the population changes very often since there are so many animals and many babies being born. While the population grows, the change and population in an ocean depends on the habitat resources and if there is enough for all the animals.
This is habitat resource changes and population change.
Definition: Any factor or condition that limits the growth of a population in an ecosystem.
Examples: Food, Water, Light, Temperature, Disease Soil Composition.
- Sharks prey on sea lions. So if the sea lion population decreased, then the shark population would also decrease.
Definition:They are determined by how the organism gains energy and how it interacts with other living things in its ecosystem
Definition: They are determined by how the organism gains energy and how it interacts with other living things in its ecosystem.
Examples: Kelp, Seaweed, Phytoplankton, Sea Grass, Red Algae
Energy: Receive their energy from the sun, the main source of energy
Vital Reason: Producers are vital to the ecosystem because they receive their energy from the sun, which is the main source of energy. They then provide energy that fuels the rest of the ecosystem.
Definition: Organisms that do not make their own food; they feed on other organisms (plants and animals). All animals are consumers.
Energy: Receive their energy from other consumers and producers
Examples: Clown Fish, Manatee, Parrot Fish
Examples: Blue Crabs, Sea Otters, Sea Turtles, Seal
Examples: Sea Lions, Sharks, Dolphin, Blue Whale
Examples: Star Fish, Eels, Sharks
Definition: Organisms that break down waste and dead organisms and return the nutrients back to the environment.
Examples: Hag Fish, Fungi, Sea Weed
Energy: Receive their energy from the dead material of the consumers
Food Chains And Food Webs
Food webs are more realistic than food chains because a food chain shows one possibility but a food web shows multiple possibilities making it more rational.
If the Tuna Billfish population was taken out of this food web then the Mesopelagics will grow because they will have lost one of their predators. Humans will have lost one source of food.
Trophic Levels And Energy Pyramids
Reason: An energy pyramid's shape shows how the amount of useful energy that enters each level — chemical energy in the form of food — decreases as it is used by the organisms in that level.
Level: Producers are in the largest level because they make their own food and have the most energy w ithin themselves. bring energy from nonliving sources into the community.
water, sunlight, and carbon dioxide are needed for photosynthesis . Glucose, sugar, and oxygen are
produced by photosynthesis.
Definition: turning or being movement of an organism toward or away from an
external stimulus, such as light, heat, or gravity.
Some examples of tropism in the ocean are phototropism, hydrotropism, geotropism. Phototropism is the way it reacts to the sunlight. Hydrotropism is the way it bends towards water. Geotropism is the way turning or growth movement by a plant or fungus in response to gravity.
These tropisms help the plant survive by getting them all of the needed resources and without it plants wouldn't be able to get enough water, heat, and sunlight.
The Role Of Decomposers
Decomposers are vital to the ocean ecosystem because they break down once living matter into the ecosystem and release organic compounds to be used by plants. Without decomposers we wouldn't have new plants because the plants wouldn't get the needed nutrients that help them grow.They also recycle the dead material and plants. We would eventually live in our own waste and everything would die without nutrients.
Types of decomposers- Fungi, Hag Fish, Sea Weed
Adaptations are important because, if an animal doesn't adapt to its surroundings it may be harm by other living objects or the weather conditions may be to harsh for the animal. There are two types of adaptations, structural and behavioral.
Honestly...If organisms from my environment were to be placed into another ecosystem, they would most likely die from too much oxygen, but there are some organisms that might be able to adapt and live on land or in another ecosystem. for instance if a sharks was to be placed into a rainforest, it wouldn't be able to move their fins, and since they are used to breathing underwater, they wouldn't be able to survive.
Definition: Is the process by which certain inheritable traits become more common in a population over successive generations.
Natural selection is important for organisms because without it the important traits that could help that species survive wouldn't be passed down and that species would die out. It also allows favorable traits to be passed on to future generations. This way the animals with the favorable traits can reproduce and survive.
