ENVIRONMENTAL RELATIONS

SOIL

• Composed of inorganic particles,air,water,and living organisms.
• Hills, valleys, and mountains affect exposure to the sun, wind, and water
• Soil forms faster in warm, wet climates.
• Plants add organic matter and affect a soil's composition and structure
• Healthy soil is essential for agriculture and forestry.

SOIL-WATER

WATER

• Energy from the sun causes water to move into the atmosphere

WATER-POLLUTION

POLLUTION

• Categories: nutrient, toxic, chemical, sediment, thermal, and biological
• Point-source pollution comes from distinct locations
• Nonpoint-source pollution comes from many places over a large area
• Natural process: wind storms, volcanic erruptions, and fires.
• Human activity: Farming causese erosion which leads to storms.

POLLUTION-PLANTS

• Plants require carbon dioxide and water
• Pollution restricts oxygen to plants.

PLANTS&ALGAE

• multi cellular organisms that require sunlight.
• Produce carbohydrates for energy
• Require carbon dioxide and water

PLANTS- ANIMALS

ANIMALS

• ectothermic: able to generate own heat
• poikilothermic: body is controlled by environment.
• Unlike plants, animals are mobile to assist in obtaining food.
