Notes on Abiotic Factors

Water:

1. All living thing need water to survive.
2. water makes up most of our body.
3. Our body is 65% water.
4. Plants and algae need water, carbon dioxide, and sunlight.
5. They use those components in a process to make their own food called photosynthesis.
6. Other living thing depend on plants and algae for food.

Sunlight:

1. sunlight is needed for most living things and for photosynthesis
2. were it is dark plants and algae cant grow.
3. only a few organisms can live in a cave.

Oxygen:

1. Most living thing need air to live.
2. You can live only a few minutes without air.
3. Organisms that live on land obtain oxygen in air, which is about 20% oxygen.
4. Fish obtain oxygen that dissolves in the water around them.

Temperature:

1. Some animals alter their enviroments so that they can survive in very hot, or very cold climates.
2. Like a prairie Dog.
3. The temperature determines the organisms that live in the surroundings.

Soil:

1. Soil is: rock fragments, nutrients, air, water, and the decaying remains of living things.
2. The type of soil depends on the type of plant that grow there.
3. Billions of little organisms live in soil.
