What is a Habitat?
Habitats can apply to one organism, a population, species or community
A habitat is where an organism lives, both geographically and the type of place. (A desert and a tundra are very different places).
This includes the physical conditions of the habitat, the type of ecosystem, and where within the ecosystem an organism lives.
What are Biotic Factors?
Biotic Factors are living things and their interactions(Species that compete, predation). These dominate in community dense ecosystems like tropical rain forests.
This often leads to competition, specifically competition in light, as trees and other plants will grow in specific ways to get enough sun to survive
What are abiotic factors?
Non-living things (temperature, water, etc). These dominate the environments that have extreme habitats and population density is low such as deserts.
This is the focus of this topic
What are the struggles faced by grass in sand dunes?
Their challenge is water conservation, tolerance of high salt and sand building up.
