Transcript of ECOSYSTEMS
Ecosystem- an ecosystem is made up of non-living and living things. The living and non-living things interact with each other. Two living things can interact with each other, two non-living things can interact with each other, and one living thing and one non-living can interact.
Organism- a living thing in an ecosystem is called an organism. These are usually plants and animals.
Micro organism- When an organism is too small to be seen without a microscope, they are called a micro-organism
Species- Each organism is put into a different group. These different groups are called a species.
Population- When a species gathers in a certain area they are called a population.
Producers: Producers are organisms that make food out of non-living materials.
Consumers: An animal that feeds off other animals in it's habitat.
Herbivores: A consumer that eat only plants.
Carnivores: A consumer that eats other animals.
Omnivores: A consumer that eats both animals abd plants.
Detritivores: A animal that feed off on other dead, decaying animal bodies.
Decomposers: An organisms that break down dead or decaying organisms
Definitions part 3
Community- When two or more populations of different species live in the same area it is called a community.
Biosphere- Because the earth is one large ecosystem we call it a biosphere. The biosphere is made up of places where living things are found.
Biome- A biome is a place that has the same temperature and precipitation.
Pyramid: Squashes, Capybara, Caiman, Anaconda
Predator Prey Interaction
Human impact on ecosystems
Humans effect ecosystems in many good and bad ways. The most popular way humans affect ecosystems is through habit destruction. This usually happens because we are trying to expand our land to build more buildings and home. Our population is growing rapidly so it is hard to avoid this. We also affect ecosystems by removing important animals, for example fishing, killing cows for beef, and hunting. we can help the ecosystems by planting trees, avoid cutting down habitats, stop machine farming, and cut down our use of cars because of pollution.
Humans also effect the environment through pollution, and these changes can be widespread. Increases in carbon dioxide and other greenhouse gases have raised global temperatures, and these increases can alter sea levels and weather patterns. Just a few degrees of change can damage fragile ecosystems by wiping out key flora or altering animals' reproductive cycles, and the fact that these gases can affect the environment for decades if not centuries ensures that their impact is long-term and widespread.
How humans effect ecosystems pt.2
Having predator prey interaction keeps ecosystems in balance. Predators kill the prey which keeps the prey from over populating. When the prey becomes close to extinction, the predator becomes hungry because of not being able to find the prey, which gives the prey time to reproduce, which starts the cycle again. Predator and prey evolve together. The prey is part of the predator's environment, and the predator dies if it does not get food, so it evolves whatever is necessary in order to eat the prey: speed, stealth, camouflage (to hide while approaching the prey), a good sense of smell, sight, or hearing.
Caiman: Caimans are smaller versions of crocodiles. They live in South America and Australia.
Anaconda: One of the biggest snakes in the world, living in South America somehow can devour a whole live Caiman.
