What’s an ecosystem
A community of non living factor and living factors interacting with eachother in a particular area
Abiotic factors
Moisture level
Light intensity
Oxygen levels
Biotic factors
New predators
One species out competing another
New pathogens
What is a stable community
When abiotic and biotic factors rarely change and all populations are kept roughly constant
What’s a community
Several different species across all kingdoms living in a habitat
What’s a population
A group of individuals of the same species
What’s interdependence
Each species depends on one another for survival
What is eutrophication
Nitrates and phosphates from fertilisers or sweage act as fertilisers for algae
The algae grow rapidly and float to the top of the surface
This blacks oxygen and sunlight for the other plants and animals below leading to death
Decreased biodiversity and damage to ecosystems
