Ecosystems: Everything is Connected “When we try to pick out anything by itself, we find it hitched to everything else in the universe.” – John Mur, American Explorer and Naturalist
What is an ecosystem? An ecosystem includes all the different organisms living in a certain area, along with their physical environment. Composed of both biotic and abiotic factors, which interact with each other.
What is the difference between biotic and abiotic factors? Biotic – the living parts of the ecosystems Animals, plants, microorganisms Abiotic – the nonliving parts of the ecosystem Temperature, sunlight, humidity, water supply, soil type, mineral nutrients
Niche vs. Habitat Niche – an organism’s way of life, how it contributes to and fits into its environment Habitat – the actual place the organisms lives in (its address)
Organisms vs. Species Organism – one individual living thing Species – a group of organisms that are able to produce fertile offspring, and that share common genes and therefore resemble one another Name Some Examples!!
Population vs. Community Population – a group of individuals of the same species living in a particular place. Ex: Bullfrog population on a pond Community – a group of interacting populations of different species Ex: A pond community includes the populations of all the different plants, fish, insects, amphibians, and microorganisms that live in and around the pond.
