Forest Ecosystem
Plants are the first energy source in ecosystems. They use photosynthesis to convert water, sunlight, CO2, and nutrients into sugar for there needs. Most of this process happens in plant leaves, where the sunlight is most abundant. Plants are producers, which are eaten by first-level and other level consumers in the food web.
Consumers cannot make their own food, so they obtain their energy from producers or other animals, or both. Consumers are classified by what they eat. Carnivores only eat meat, herbivores only eat plants, and omnivores eat both of them. Consumers are ranked in certain levels on a energy pyramid for what they eat and obtain energy from. Scavengers feed on dead animals for food, such as vultures who scan the ground for dead meat. There are many more animals, such as owls, that are not included here.
This weasel roams the Northeast Asian deciduous forest. It is one of the smallest carnivores in the world. It has sharp nails and a slender body. The fur is brown and white, and the weasels will mark a territory for themselves. The least weasel has short legs, black eyes, and a very good hearing. A mother raises 3-10 babies at a time, without the fathers help. They eat mice, rats, moles, small birds, bird's eggs, rabbits, and poultry. Their predators are hawks and owls. They can kill prey up to 5 times their size, and live for about 2 years in the wild.

This plant can grow 2-3 feet tall and has many rough-textured leaves. Many sprouts come out of one central stem in the ground. They actually prefer to grow in shaded areas! Instead of seeds, ferns use spores to reproduce. Grizzly bears and elk will eat this plant as a food source. These plants mostly cover parts of the forest floor.

Predator/Prey/Omnivore
This strange animal has thick fur, a flat body, a tail, and a large bill. Males have spurs on their ankles that carry venom for defense. It can b 26 to 39 inches long, and they have nostrils which they close when they go underwater. They live up to 15 years, and lay eggs which produce baby platypus that are raised by the female. They have webbed feet and a flat tail that help them swim well. They eat frogs, shrimp, fish, and tadpoles. They have burrows in the soft mud near riverbanks, which is where they live.
The Shagbark Hickory tree has an ashy grey-colored bark that peels into strips, which makes it look very shaggy. This tree grows very straight and up to 100 feet tall. The wood is very strong and tough and the branches can spread to about 25 feet from the trunk. The leaves grow in groups of 5 or 7 and can be very large. The tree also produces sweet nuts and small flowers.
This small animal weighs about 3 ounces. It has brown-redish fur with stripes that are found all over the body. They make a chattering noise when they are upset. They have small, concealed dens in which they sleep and live in. They do go into hibernation, although they may move around if the weather is warmer. Parents raise families of 2-5 babies, which are left on their own at 2 months old. These animals eat grains, nuts, berries, seeds, bugs, and bird eggs. They store food underground so they can have a constant supply of food.

Welcome to the deciduous forest ecosystem. Many animals thrive and interact with each other to form this ecosystem. These forests are found in the eastern US, Europe, parts of Russia, China, and Japan, as well as parts of Canada. The seasons are distinct, and the temperture can rise and fall drasticlly in winter and summer. There is a good amount of rainfall, and many of the plants and animals have adaptated to this ecosystem through natural selection. Some of the organisms here are not located in all of the regions of this forest, but in general, the organisms in this presentation live in the temperate deciduous forest in some region of it. Also note that there are many other animals and plants besides the ones shown here. They might include racoons, owls, and certain snakes, as well as sweet gum trees and hickleberry bushes.

Abiotic Factors
Adaptations
Birds of prey/bears/coyotes
Abiotic factors are the non-living things in an ecosystem. But, they are necessary to support the life in a specific ecosystem. They include:
2nd Level Consumers: bears/birds/weasels,etc.
Many plants and animals have adapted to this ecosystem. The trees and plants have learned to lean to the sun for more sunlight. Many animals use the trees to hide and escape danger. Many animals have camouflaged fur to blend in with their surroundings, like the white-tailed deer. Many animals have sharp senses to help them survive. This is all the work of natural selection.
1st level Consumers: deer/insects/rodents,etc.
Water: needed for all living things to survive in a ecosystem-some ecosystem have more than others.
Sunlight: needed for photosynthesis-keeps producers alive in an ecosystem.
Oxygen: needed for most living things-produced by plants and used by other organisms for life.
Temperature: needed to determine what animals live in an ecosystem-animals can adapt to their ecosystem's temp.
Soil: Allows plants to grow and obtain nutrients-provides homes for many animals and microscopic organisms.
Producers: bushes/trees/moss
Decomposers
Populations
Sometimes animals will immigrate and emigrate in and out of a ecosystem, especially if food is in low supply for a specific animal. If, for example, a bigger type of squirrel immigrates into this ecosystem in Europe, the european red squirrel may not be able to compete for food and space with ths animal. This could cause the population to decrease, and eventually, the european red squirrels to emigrate to another place. The emigration and immigration of animals often throws an ecosystem off balance. Also, the birth rate and death rate of a population of animals may rise and fall over time, which will change the ecosystem.
Fungi are molds, yeasts, and mushrooms that break down and feed on organic matter. These decomposers are found in this ecosystem.
Worms, beetles, flies, and maggots are examples of insects that break down and feed of of dead organic matter. Many of these bugs ive iside of dead logs and trees, where they break the plant down.
Decomposers recycle energy and nutrients in an ecosystem to keep it healthy.

Bacteria can be in soil and plants breaks down dead matter, and sometimes can harm plants that are living. The bacteria are not visible to the naked eye.
