Carrying Capacity :

The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

Changes over time

Changes over time in my ecosystem consist of no food, space, or shelter. When not having the right demands of food supply they become cannibalistic or die. Shelter is a big factor in my ecosystem knowing that the majority need and place to hide from their predators causing them to be found and eaten. Another change is the reproducing in the ecosystem.

Limiting Factors

A factor that limits the growth of a population in an ecosystem is: food, light, weather, diseases, etc...     

Sharks are the predators for many fish in the sea.The sharks will just swallow them whole. Another example is eels, fish can hide from eels in their shelter, the anemone, to protect themselves from the eels.The limiting factors affect them by killing them.

Energy Roles

Some examples of energy roles are fish, sharks, and kelp. The fish nibbles on the kelp which gives the fish energy, and the shark eats the fish which gives the shark energy(plants get energy from sun).

Food webs

Food webs are more realistic because they overlap showing more possible outcomes while food chains only show one section of the web.Food webs show more possibilities of how the energy flow is transfered from one organism to another.

If you removed the other seals from the population then the krill would start to over populate and the phytoplankton would soon decrease.With the phytoplankton decreasing it would soon die off,then the other herbivorous zooplankton would die without food,then killing the krill and carnivorous zooplankton.

Producer: coral

Primary consumer: clown fish

Secondary consumer: stingray

Territory consumer: reef shark

As you see here in my pyramid shape it  shows that the energy goes from 100% all the way down to 1%. The pyramid shows that from the 100% of energy the producers take in  from the sun that total amount of energy transfers downward so each time the next consumer takes 10% of the energy from the previous organism knowing that it uses 90% of it to live. While in a cylinder it would not show the change of energy getting smaller from the base to the top losing more and more energy each time an organism takes energy from the previous.

Photosynthesis

Photosynthesis Process

Water, sunlight and carbon dioxide are the components that let a plant/producer go through photosynthesis.

CO2+H2O--->C6H12O6+O2

The chloroplast will take in radiant energy, then the chlorophyll (inside the chloroplasts)take in that radiant energy , and turns it into chemical energy.

Tropisms

A tropism is a turning or bending movement of an organism toward or away from an external stimulus. For example sea grass is a positive tropism because it grows toward the light.

Decomposers

Decomposers help our environment by removing waste and turning it into nutrients, some of the decomposers in my environment are clam worms, sea urchins, and bacteria. Without these guys helping us out, our ecosystem would contaminate and pile up with waste(gross).

Adaptions

And adaption is when it organism changes the way it live to the way it needs to live in that environment. Some examples are fur, gills, night vision, bioluminescence, playing dead, camouflage,speed and new types of shelter.

Adaptions that a plant would need

Adaptions that plants would need are growing taller(Seaweed, kelp), less or more sunlight( depth of the plant), and defense mechanisms(poison)

Adaptions that an animal would need

Adaptions that animals would need are, faster swimming,new types of food(cannibalism,omnivore),traveling in bigger or smaller schools, shelter(coral reefs), containing poison/venomous, camouflage(Color of coral or sand),and bioluminescence.

In a new place

Placing an organism from my environment and placing it into a new one would probably shock it and kill it knowing that my animal has spent its entire life adapting and living in that first environment. Perhaps you put a clown fish into an environment 5 miles away it would not know where to hide or find its food. The clown fish would be quickly eaten by a predator of that new environment or die of no food.

Natural Selection

The process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations.
