Carrying Capacity

The largest number of individuals of one species an enviroment can support

Resources needed: shelter, food, and water.

Lepards are carnivores and prey on birds. If the climate gets cold and the birds migrate, leopards won't have food to eat. Also if the tropical rainforest doesn't get enough sun the plants will die and the birds will have no trees to live in. So there would be no food for the leopard. and the leopard wouldn't have trees to camouflage into.

Limiting factors

Things that limit the population in size


-river droughts




A limiting factor of sunlight can cause plants to not grow; and if plants don't grow deers won't have food to eat and could decrease in population. If the deer population decreases the jaguars won't have deer to eat and could decrease also.

Oh deer!

Energy roles

Producer: produces food with photosynthesis (autotroph)
comsumer: an organism that eats other organisms (heterotroph)
decomposer: an organism that breaks down waste and brings back nutrients

Bromeliad are a producer.

Chimpanzee is a herbivorous consumer.

Ocelot is a carnivorous comsumer.

Saprophytes are decomposers.

Blue and grey tanagers are omnivorous consumers.

Each energy role gets their energy from some type of thing. The producers get their energy from the sun. The consumers get their nutrients from the organisms or producers they eat. Decomposers get their energy from the waste that they break down.

Producers get their energy from the sun because of all the energy it gives. Without the producers the rest of the ecosystem would not live. Since the primary consumers get their energy from the producers the other levels wouldn't get to eat the other levels.

Food webs and food chains

Food webs are more realistic than food chains because it has more than possibilities to go from.

If the boa constrictor population got removed; the sloth and golden lion tamarin population would grow because nothing is eating it or they have one less predator. Also the jaguar would have more golden lion tarmarins to eat.

Trophic levels

The pyramid shows the levels that have the most energy and least energy. The bottom shows the most and as it gets towards the top it gets less energy and is smaller.

The producers are at the bottom because they have the most energy from the sun and start everything off. The top is smaller because of how gradually the energy gets smaller and there is less energy at the top from all the other animals below it taking the energy. This represents chemical to mechanical energy.


The process of which plants produce sugar/energy

CO2+H2O+light -> C6H12O6+O2

CO2: carbon dioxide

H2O: water

C6H12O6: sugar

O2: oxygen

Light, water, and carbon dioxide is need for photosynthesis to occur. It then produces sugar/glucose.

Photosynthesis in a plant cell


Turning or bending movement of an organism toward or away from an external stimulus, such as light, heat, or gravity

Phototropism helps the tropical rainforest because plants under the tree canopy they need to find light; and the light may be shining in another direction so they lean towards the light.

Thigmotropism also helps if a plant needs to wrap around other trees or objects to get what they need.


Decomposers are very vital because they are the organisms that break down all the waste consumers produce. Also decomposers are the organisms that bring back the nutrients back for plants. If decomposers died out we would be walking in our own filth. Also plants would die out without nutrients then consumers would die out.

Types of decomposers



Adaptations help organisms be able to survive a habitat. Also they let organisms have traits to easily live in that environment. Some adaptations are flying, webbed feet, thick/short fur, etc.

Monkeys' hands are an adaption. They have padded and opposable fingers to eat and climb trees.

Trees have thick bark to adapt to store water better over a longer period of time.

If the monkeys got put in a cold environment, they wouldn't be able to keep warm with the little fur they have; and they would freeze to death.

Natural Selection

The process where organisms better adapt to an environment

An example of natural selection is if there were leopards born with spots and leopards born without spots; the one without spots would have a difficult  time getting food. The spots allow them to hide easily to catch their prey without getting caught. Leopards with no spots would let the population they eat grow, because they aren't able to hide.

No spots

Look at capitalization on some of your factors...keep it consistant. Also, you don't need periods at the end of the definition for biotic and abiotic.
