Abiotic Factors:non-living things in an ecosystem
Biotic Factors:living things in an ecosystem
Carrying Capacity:the largest number of individuals of one species that an environment can support.
There are many resources that are needed in the rainforest in order to survive.
There are a lot of resources needed,but what if they were to become scarce?
If the rainforest were to be short on space because of the many different types of organisms that are living there, then the ecosystem itself as a whole would be affected if that resource was scarce.
This causes a build-up and this means that some of the organisms in the rainforest wouldn't be able to function in the rainforest,causing a decrease in population.
Limiting Factors:any factor or condition that limits the growth of a population in an ecosystem.
One example of a limiting factor in the rainforest is the anount of sunlight.
A predator in the rainforest could be a short-tailed fruit bat, and it's prey could be an insect. The limiting factor in the ecosystem ,the sunlight, affects this predator prey relationship in many ways.
It starts with the sun and plants. If the plants can't get enough light from the sun,then the consumers that eat the plants probably won't be able to get those plants, and if the insect can't eat the bat doesn't eat.
Energy Roles:determined by how the organism gains energy and how it interacts with other living things in its ecosystem
The three main energy roles are a producer,consumer,and a decomposer.
Producer: Canopy tree
Consumer: Tree frog
The canopy trees get their energy from the sun. The caterpillars get their energy from the canopy trees. The tree frogs get their energy from the caterpillars. The Jaguars get their energy from the tree frogs.(this happens with cub Jaguars)
Producers use the sun's radiant energy and then turn it into chemical energy, which is being eaten, and then that energy turns into mechanical energy and thermal energy. This energy is being transferred to each organism as it eats the previous thing.
Food webs are many food chains put together. Food webs are more realistic becacause it shows all of the possible flows of energy for each organism in an ecosystem.
Because the snake would be considered a tertiary consumer, this means that no other organism would eat this snake unless they were a quadinary consumer.
An energy pyramid shows the amount of energy transferred to the organisms.
This energy pyramid is in the shape of a pyramid because as the energy flows toward another organism the other organisms below that have to be eaten by the ones above.
Producers are the largest level because it starts the flow of energy and it also contains the most energy at first. Top predators are in the smallest level because they have the least amount of energy and they can't be eaten by any of the organisms below it.
The things needed for photosynthesis are: water,sunlight,and CO2. The items produced by photosynthesis are glucose and oxygen.
Photosynthesis takes place within the chloroplasts of the plant cell.
Energy Transformation: Chemical to Radiant
Tropisms: a turning or bending movement of an organism toward or away from an external stimulus, such as light,heat, or gravity.
Even though this tropism is a negative one towards the plant, it could benefit the organism that consumes it. This tropism would be considered geotropism.
Decomposers are very vital because they help recycle nutrients back to the producers.Without them we wouldn't have many well nutritious producers that provide food for other organisms.
Some examples of decomposers in the rainforest are: saprophytes, mycorrhizals, and the velvet worm.
Natural Selection:the process by which certain inheritable traits become more common in a population over successive generations. It is important because it creates extra space, more room for other organisms in this ecosystem, and it is basically the reason for the change in our environment.
For example, tree frogs of different colors are going to be eaten. The red frog is very easily seen,unlike the green frog, which blends in with its surroundings. A bird flies by and eats all the frogs it possibly can. Now the red frog population has decreased, and the green frog population has increased. Now because the red frog as decreased ,the only frog left to eat is the green frog. Because they blend in with their surroundings, they won't be eaten as much. This use of camouflage will create competition between all organisms who eat the frog.
