PRESENTATION OUTLINE
abiotic: nonliving things in an ecosystem.
biotic: living things in an ecosytem. Foxes are biotic because they are living organisms.
Ecosystem: community of interacting organisms and their physical environment.
Population: all of the inhabitants of a particular town area or country. The population in cities are greater than towns or other areas.
Community: a group of people living in the same place or having a particular characteristic in common.
Habitat: a natural home or environment of an animal, plant, or their organism. An animlas habitat is like its home.
Niche: the role a species plays in a environment.
Predators: an animals that preys on others. Lions are predators because they eat other animals.
Prey: animals being fed on by other animals. Zebras are prey to lions.
symbiosis: interaction between two different organisms living in close physical association. butterflies have a symbiotic relationship with flowers because they get food from them.
Mutualism: symbiosis that is beneficial to both organisms. Flowers and bees have a mutualistic relationship with bees because they both depend on each other.
Parasitism: a non-natural symbiotic relationship where one benefits at expense of the other. Mosquitos and humans have a parasitic relationship because the mosquito benefits from the human.
Producer: Plants that makes their own food. Grass us a producer because it is a plant and it makes its own food.
Consumer: Organisms that obtain energy by consuming other organisms. Humans obtain evergy by eating.
Herbivore: an organisms that eats only plants. Deer are herbivores because they eat only plants.
Carnivore: an animal that eats other animals. Tigers eat other animals.
Omnivore: are animals that both plants and animals. Bears are omnivores, they eat plants and animals.
Food Chain: shows how eachthing in an environment gets food and how energy is passed. Animals have obtain energy from eating a producer or another animal.
food web: a system of interlocking and independent food chains.a food chain is similar to a spider web because the animals are connected somehow.
pyramid: relationships in the food chain, in which various forms of life are shown on different levels.
water cycle: The process by which water circulates between the earth's oceans, atmosphere and land. The water cycle occurs mostly at the ocean.
carbon cycle: the cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere. carbon is most abundant in the atmosphere.
oxygen cycle: the movement of oxygen within its three main reservoirs: the atmosphere(air),the biosphere, and the lithosphere. trees give off oxygen.
Succession: observed process of change in the species structure of an ecological community over time. Trees go through the process of succession.
Biome: a large naturally occuring community of flora and fauna. The jungle has a large number of animals and plants.
Biosphere: regions of the planet that are occupied by life.Most of earth is occupied by life.
Biomass: total mass of organims in an given environment. liquid biofuels are part of the biomass.
