Ecosystem Relationships
Ecosystems:
An ecosystem consist of both non-living and living factors. The forest is an example of a huge ecosystem. There are two parts of an ecosystem, abiotic and biotic. Abiotic are non living factors of an eco system such as rain, sunlight, and temperature. Biotic are the living factors of an eco system such as plants, animals, and bacteria. biotic and abiotic factors work together for an ecosystem to survive and flourish.

Changes in ecosystems:
People and nature affect the balance of an ecosystem, so they can change everyday even just by a little bit. When those change happen they cause succession. Succession is the gradual growth of new organisms in an environment. There are two different types of succession. Primary and Secondary successions. Primary succession happens when a brand new ecosystem begins to take place. Secondary succession happens in an ecosystem when the first has been wiped out and a new one starts to take place.

Symbioses:
Symbiosis is the relationship between two organisms in a community. There are three types of symbiosis: Parasitism, Commensalism, and Mutualism . Parasitism is a relationship that only benefits one organism and harms the other. Commensalism is a relationship in which one organism benefits and the other organism is not harmed. Mutualism is a relationships is when both organisms benefits.

Biomes:
A biome is a major ecosystem made up of many habitats. There are 6 different biomes on planet earth: Taiga, Tundra, deciduous forest, tropical rainforest, desert, and grassland. The main difference between these 6 biomes are its climates.
Deciduous Forest:
~It's the only biome with 4 seasons ~Trees bloom in the spring and loose leaves in the fall ~ Foxes, bobcats, and song birds live here. Tundra:
~This climate is so cold that no trees can grow ~Dwarf-like plants bloom for only 8 weeks a year ~Polar bears, Reindeer, and Caribou live here |
Tropical rainforest:
~Leopards, toucans, and monkeys live here ~Climate is warm year around ~Heavy rains help keep forest lush and green. Desert:
~Climate is very hot and dry ~It receives less than ten inches of rain a year. ~Because of this all the plants and animals that live there have adapted to receiving very little water ~Iguanas, lizards, beetles, and jackals live here |
Taiga:
~Largest biome of all ~Stretched across Canada, Europe, and Asia Has two seasons: Cold winters & Warm summers. Grassland:
~Found in Unites States, Africa, Asia, and South America ~Grains like corn, wheat, and barley grow here. ~Gazelles, zebras, and rhinos live here ~Hunters like lions, tigers, and hyenas live here too |

Further Questions:
What is biodiversity and how does it affect the ecosystem?
Biodiversity is the variety of living things in our environment . Biodiversity affects our ecosystem by preventing there being a limited number of prey for the predators and vice versa. Without it, most organisms would die from lack of variety or the limited amount of things to consume.
Where does the energy for all ecosystems originally come from?
All the energy for the ecosystems originate from the Sun. From there they are distributed to the producers.
Why do all organisms in an ecosystem depend on producers?
The producers are the only biotic factors that can receive energy from the Sun. Without the producers , there would be no way to receive energy , for all the energy would come to earth, but have nothing to absorb it. Organisms depend on the producer to obtain energy.
How does a food web help show feeding relationships in an ecosystem?
A food web shows where the energy originally originated from, after it came from the Sun. From there it shows arrows to show where 10% of the energy went once that producer was consumed. It goes on until it reaches the top of the food chain, where eventually the energy will die inside of the organism , and the decomposers will take all the remaining energy.
