- Ecology
- Communities
- Abiotic Factors
- Light intensity
- Temperature
- Moisture Levels
- Soil pH and mineral content
- Wind intensity and direction
- Carbon Dioxide levels for plants
- Oxygen Levels for aquatic animals
- Biotic Factors
- Availability of food
- New predators arriving
- New pathogens
- One species outcompeting the other, so the other cannot breed
- 2 or more populations of organisms
- Abiotic Factors
- Extremophiles
- Types of extremophile
- Thermophiles
- acidophiles
- Psychrophiles
- alkalophiles
- barophiles
- xerophiles
- halophiles
- anaerobes
- Microorganisms that thrive in extreme environments
- have special adaptations that help them to survive
- live where other organisms would find difficult or impossible to survive
- Types of extremophile
- Food chains
- All food chains start with a producer
- Green plant
- The primary consumers are herbivores
- they only eat plants
- Carnivores are secondary or tertiary consumers
- No more than four consumers in a chain
- Not enough energy left
- Stages in the chain are called trophic levels
- as you go up the chain, numbers decrease but sizes of the organisms increas
- Final predator is called the top predator
- All food chains start with a producer
- Competition
- Plants
- Light
- Water from soil
- Minerals from soil
- Space
- Animals
- Food
- Mates
- Territory
- Water
- Light
- Plants
- Communities
