What Are the 5 Koppen Climate Classification Types?
The Koppen climate classification catalogs Earth’s types of environments, which include tropical, dry, temperate, continental, and polar.
Natural Environment
What Are the 4 Levels of the Food Chain?
All living things rely on each other in the food chain. Energy transfers through living organisms from predators, herbivores, producers and decomposers.
The Biosphere: Life on Earth
The biosphere is the layer of Earth where life exists. You, me, plants, insects bacteria and all living things on land, air and oceans are the biosphere.
Nutrient Cycle: From Inorganic to Organic Material
Food for thought, the nutrient cycle constantly exchanges inorganic and organic matter back and forth in the environment. It’s just recycled back and forth.
What Is Biodiversity (Biological Diversity)?
Biodiversity or “biological diversity” refers to the variety or genetic diversity of species in an ecosystem. Ecosystems rely on biodiversity for resiliency.
Long-Term Carbon Cycle: Carbon Dioxide to Hydrocarbons
Carbon is re-purposed into fossil fuels in the long-term carbon cycle. The coal that we use today was produced millions of years ago from buried swamps.
What is Net Primary Productivity for Earth?
The Earth breathes. We gauge Earth net primary productivity by how much carbon dioxide plants absorb from the atmosphere minus how much it respires.
Photosynthesis Process: Carbon Dioxide to Glucose
The main idea of photosynthesis is it takes carbon dioxide from the air. Then, it uses carbon with water to convert it into a chemical form like glucose
How Trees Grow from Carbon Dioxide and Water
For the most part, trees growth is from carbon dioxide and rain water. So most of the dry mass of trees is made from the contents of the air and water.
What Is the Carbon Cycle? Photosynthesis, Decomposition, Respiration and Combustion
Carbon is essential for living things and making cars move. It takes up various forms through photosynthesis, decomposition, respiration and combustion.
What Are the 4 Steps of Nitrogen Cycle?
Nitrogen transforms into several different forms in the 4 steps of the nitrogen cycle – nitrogen fixing, decomposition, nitrification & denitrification.
