Transcript of An Unbalanced Ecosystem


Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.
The abiotic factors, such as wild fires, in the Amazon Rainforest have devastating effects on the biotic factors, since their habitats get destroyed.
Rain, wind, temperature and the overall climate has effects on the animals and plants such as supplying them with food and growth.
Biotic & Abiotic Factors
Populations & Communities
Population- is a group of organisms that are the same species living together in a certain area.
Food Chain
Producers & Consumers
Indicator Species
- A species whose presence, absence, or relative well-being in a given environment is indicative of the health of its ecosystem as a whole.
Influences that Result in an Imbalance
Deforestation impacts changes in temperature causing the forest floor to become dryer. The plant matter that was once there before deforestation helped keep the ecosystem together but due to deforestation, the lack of trees increases wind and flood rains to impact the forest floor which raises the chance of erosion. The ecosystem on the forest floor becomes unbalanced due to the change in temperature and the amount of water received. Deforestation also has affects on animals source of food and shelter.
The major causes of the decline in a diverse community in the rainforest are land use changes, pollution, changes in carbon amounts, and the introduction of exotic species, all coincident to human population growth. Which results in an imbalance.

Abiotic and Biotic Interactions
Terrestrial Ecosystem in the Amazon Rainforest
Biotic factor- a living factor that influences an organism

Ecosystem
An ecosystem can be defined as a community of plants and animals associated with specific climatic conditions and abiotic features, the interactions that take place between animals, plants, soil, nutrients and other living organisms within a specific area.
Abiotic Factor- a non-living factor that influences an organism
temperature, water, rocks, sunlight, climate, and weather
Community- is different populations in a certain area that interact with each other in some direct or in direct way.
Scientists estimate that there are more than 50 million different species of invertebrates living in rainforests.
The majority of tropical rain forest plants rely upon animals for pollination. Insects, birds and mammals pollinate the plants inadvertently by transferring pollen from flower to flower in their quest for food.
Human Impacts
Herbivore: an animal that feeds on plants.
Capybara
Howler monkey
Tapir
Macaws
Carnivore: an animal that feeds on flesh.
Green anaconda
Harpy eagle
Venus fly trap
Jaguar
Omnivore: an animal or person that eats food of both plant and animal origin.
Toucan
Poison dart frog
White faced saki monkey
Squirrel monkey
Tropical frogs are specialized animals and are very sensitive to changes in their environment. This results in an excellent indicator as to how well the ecosystem of the rainforest is doing.
Humans have impacted the Amazon Rainforest negatively by deforestation. This has resulted in smaller habitats for animals and plants to live in, thus slowly decreasing the population and communities.
With the decrease in trees, this increases the chance of wildfires in the rainforest and chance of erosion. Which, in turn destroys the ecosystems all together.

Amazon Rainforest
Facts
The Amazon rainforest ecosystem is described as the “Lungs of our Planet.” Its vegetation continuously recycles carbon dioxide into oxygen. About 20% of the earth’s oxygen is produced by the Amazon rainforest.
Scientists believe that the canopy may contain half of the world’s species.
The Amazon rainforest ecosystem consists of four communities. Each community has unique ecosystems, plants, and animals adapted to that system.
