carrying capacity

The carrying capacity is the number of animals in a species.

The population of organisms in the ocean decreases everyday because of humans. Hundreds of fish die everyday cause fisherman catch them and more than likely they eat them instead of putting them back. All animals in the ocean suffer everyday because of pollution and trash ending up in the ocean.

limiting factors

Limiting factors are factors that limit population growth

So if the certain type of squid whales eat became extinct. That would affect the whales and limit the population growth.

Energy roles

Energy roles are like producers, consumers, and decomposers

Ex:

Producer: seaweed, phytoplankton,

Consumers:

-HERBIVORES-> snails and clams

-CARNIVORES-> seals, whales, and certain types of fish

-OMNIVORES-> sea turtles, whales, sharks

-SCAVENGERS-> seagulls, crabs

Decomposers: bacteria, beach flies, briophite

Each of the energy roles receive its energy from whatever they consume.

Producers are vital to an ecosystem because that's where consumers get their energy.

Food chains and food webs

Food webs are more accurate than food chains because it's several food chains joined together. Most organisms depend on more than one species for food.


If the limpets were removed from the ecosystem the algae would over populate.


Tropic levels and energy pyramids

We use pyramids instead of cubes or other shapes because it displays the amount of useful energy at each level and decreases as the energy is used.

Producers are the largest level because they have the most energy. Tertiary consumers are the smallest level because they get the least amount of energy.

10% of the energy is available to whichever organism consumes it.

photosynthesis

chemical equation: CO2 + H2O -----> C6H12O6 + O2

Carbon Dioxide and sunlight is needed for a plant to photosynthesize.

Oxygen and glucose is produced by photosynthesis.

Photosynthesis takes place in the chloroplast.

tropisms

A tropism is the turning movement of a biological organism.

Seaweed, cape pondweed, pondweed, and water shield are examples of tropism a found in this ecosystem.

The role of decomposers

Decomposers are important because they break down  dead plants and animals and their waste. If  there weren't any decomposers plants would not get essential nutrients and dead matter/waste would pile up.

Phytoplankton and zooplankton are types of decomposers in the ocean ecosystem.

adaptations

Adaptations are important because certain skills/abilities are needed to required things in your environment.

Examples of adaptations in the ocean ecosystem are gills on fish and fins on sharks, dolphins, etc.

If this organism was placed in a different environment then they would have to learn to adapt to their surroundings.

Natural selection

Natural selection is the gradual process where traits becomes more or less common in a population.

Examples of natural selection would be how a Great white shark has a grey/blue top and a white bottom so it blends in with its surroundings depending on how you look at it. Natural selection is important because it allows the environment to choose better traits.

Tropism helps plants in the ocean by giving them the light they need and helping them grow towards  the light source to photosynthesize.

I agree with this because you explained everything thoroughly, however I recommend you type in complete sentences.
