Transcript of FOREST ECOSY

FOREST ECOSYSTEM.
Producers are green plants that make their own food by taking in sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things such as wood,leaves,roots, and barks. Trees such as the Oak tree shrubs ,grasses, flowers, and the American Beech are examples producers.
PRODUCERS
CONSUMERS
Consumers have to feed on producers or other consumers to survive. Deer and Zebra are herbivores which mean they only eat plant (producers). Black bear, Jackal, vultures are scavenger which eats anything even other animals prey. Omnivores eat both plants and meat. Carnivores eat herbivores and other animals to survive. Hawks, Eagles, Crocodiles and lions are examples of carnivore.
DECOMPOSERS
Decomposers take all the dead animals and plants and break them down into their nutrient components so the plants can use them to make more food. decomposers in Forests come in many different size and shapes. Shelf fungus a fungue that grows at the sides of the trees. Decomposers eat and digest for several years and turned into dirt which is good for the plants. Earthworms, bacteria, Fungi, Actinomycetes are all examples of decomposers.
WHAT IS A FOREST ECOSYSTEM???
Forest ecosystems are dominated by trees that can mature to at least 2 meters in height . With all the native wild life including birds, mammals, amphibians, reptiles, insects, plant, micro-organisms and non-living things such as water, soil and air interacting with in the same area. Non-living things can also be referred as ABIOTIC factors while living things are often called BIOTIC factors

INTERACTIONS
Biotic elements interact with other elements to meet its basic needs. For example plants use sunlight, soil, and water to grow. Animals use leaves, branches, trees, and soil for shelter and other living-things use it as food. Deer eats plants, bear eats berries and fishes. Feeding interactions give living things the nutrients they need to survive.

HUMAN IMPACT
Humans harm the environment by causing global warming , habitat destruction, acid deposition, and cutting trees. Each effect demonstrates the conflict between humans and their surrounding species.
FOOD CHAIN
Goat eats plants a Jackal eats a goat and then the Lion eats the Jackal.
A Rabbit eats a plant and a mouse a rabbit is eaten by Jackal or wild cat and then the lion eats the Jackal or wild cat. A Mouse is eaten by a rabbit, wildcat, owl or snake and then the snake is eaten by a Kite.
ENERGY TRANSFER
Energy is transfered by plants. The plants get the energy from the sun the primary consumers(herbivores) eats plants(producers) and then the secondary consumers(consumers) eats primary consumers(herbivores). The Tertiary consumers (carnivores) eats secondary consumers.

CYCLING OF MATTER
Plants use abiotic elements such as sunlight, nutrients in soil, and water to make food . Plants are food for herbivores. the herbivores are sometimes food for other consumers. Plants and animals grow, reproduce, produce waste, and in time they die. Scavengers and decomposers feed on organic wastes and remains. This process breaks down once-living matter into simple abiotic elements. Abiotic elements are made yp of minerals. These minerals are nutrients that biotic elements such as plants need to survive.

COMPETITION
Living things living in one society compete for resources like food, water, and habitat the compete because these resources are limited. Which means living are always struggling to meet their basic needs. In a forest plants compete for sunlight the tallest plants get more sunlight than the shorter plants. Two or more animals might fight for resources that are very limited. For example two lions might fight for a prey or two or more foxes might fight for a rabbit.
BIOINVASION
The term Bioinvasion means introduction of foreign species into a native ecosystem. Many of the new species are sometimes more stronger than the native species. Invasive species damage land and water. In a forest 14 percent of the species are invasive Ailanthus is an example of an invasive species.
