Very little sunlight
Carrying capacity is the largest number of individuals of one species that an environment can support
Resources needed to survive:
Changes in Population
A lemur eats fruit as a primary food source. If the sunlight doesn't reach the bottom of the forest then the fruit plants that the lemurs eat won't get enough sunlight and the lemurs would have to fight its species to survive.
Any factor or condition that limits the growth of a population in an ecosystem
There is very little sunlight that gets to the bottom floor of the forest. The three toed sloth depends on leaves to provide food and energy so if the trees don't get enough sunlight and die the sloths won't have enough food to survive. If the sloth population lowers then it will effect the jaguars' food source.
- Organisms that make their own food by photosynthesis
- Examples: Trees, grass, shrubs, ferns, flowers
- Producers get their energy from the sun
- Producers get their energy from the sun and they other energy roles depend on the sun energy to be able to move
- Organisms that do not make their own food
- ALL ANIMAL ARE CONSUMERS
- Examples: Jaguars, Lemurs, Sloths, Macaws, Snakes
- Consumers get their energy from producers
4 Types of Consumers
- Herbivores eat ONLY PLANTS
- Carnivores eat ONLY ANIMALS
- Omnivores eat both
- Scavengers eat the dead
- Organisms that break waste and dead organisms and return the nutrients back the environment
- Examples: Saprophytes, Velvet worms, Vermilion Waxcap Mushrooms, Fungi
- Decomposers get their energy from consumers
Food webs are more realistic than than food chains because they show more possibitlies.
If I remove the white tail deer then there will be an excess in bark and the grey wolf would have one less prey so they would have to eat more of the eastern cottontail rabbit and the tufted titmouse which than means less food for the garter snake and the bald eagle.
The pyramid show that the higher up it gets the least original sun energy there is. As well as the decrease of predators to prey.
Producers have a larger number because they make enough for primary consumers and if there is not a lot of producers then less energy can be transformed. The top predators don't pass on very much energy and they have less to supply with the energy because they have very little sun energy left
Tropism is turning or bending movement of an organism toward or away from an external stimulu
The tropisms help the plants get the resources they need and not get the resources they don't need.
The Role of Decomposers
Decomposers break down dead plants and animals and if they weren't in the ecosystem, the plants would not get nutrients the soil needs, and dead animals, plants, and waste would pile up.
Types of Decomposers
- Cup Fungus
- Oyster Mushrooms (Fungi)
- Leaf Beetles
- Vermilion Waxcap Mushrooms
- Velvet Worm
- Partula Snail
Adaptation is a change or the process of change by which an organism or species becomes better suited to its environment.The purpose of adaptations are to ensure reproduction and survival of the species. In the rainforest, there are so many animals competing for food, many animals have adapted by learning to eat a particular food eaten by few other animals. Toucans adapt in the rainforest by developing long, large bills. This adaptation allows them to reach fruit on branches that are too small to support the bird's weight. The sloth uses a behavioral adaptation and camouflage to survive in the rainforest. It moves very slowly and spends most of its time hanging upside down from trees. Algae grows on its fur giving the sloth a greenish color and making it more difficult for predators to spot.
Tigers have fanged teeth so they and kill and eat their prey. The venus flytrap has long sharp teeth to let it eat its prey and the color of it helps it camouflage.
If you placed a toucan in the marine ecosystem the bird wouldn't survive because their body isn't meant for large amounts of water. Toucans have bills to get their fruit from small trees but in the ocean there isn't the type of fruit they eat there.
Natural selection is the process that organisms better adapted to their environment tend to survive. This is important because if the organisms survive they produce more offsprings and the generation continues.
Around 4 million years ago, the tiger species split into two sub species due to a dramatic rise in sea level. The Tigress weber species and Tigress flippos species were both created.The species of tigers with webbed paws still had its same paw structure, so it could travel on dry land efficiently. The species of tigers with flippers instead of paws could swim very fast, but because the structure of its hand changed, it was no longer able to travel on dry land. The species of tigers with flippers were favored for a while because the sea level was so high. Many animals adapted to hunt for food in the water since most of the land was flooded. When the sea levels dropped back to their normal level, it caused this species of tigers to become extinct. The species of tigers with flippers was, and still is, successful and when the sea level rose, it developed webbed paws that were able to navigate through the water easier. Even after the sea levels dropped back to normal, the problem had been solved because it still had its paws unlike the species of tigers with flippers.
