Ecological Pyramid
A graphical representation of the trophic relationships between organisms.
Conservation Biology
The study of how to protect nature and restore ecosystems that have been damaged.
Biodiversity
The wide variety of all forms of life on Earth or within a specific ecosystem.
Natural Resources
Materials found in nature that are essential for sustaining life.
Indirect Value (Biodiversity
Intangible benefits from biodiversity, such as aesthetic, cultural, or ethical value.
Sustainability
Using resources in a way that maintains ecological balance for future generations.
Renewable Resources
Resources that can be replenished naturally or reused without depleting them.
Climate Change
A long-term shift in global or regional weather patterns.
Know all consumers in food chain and which is most plentiful
Primary consumers eat producers; secondary eat primary; tertiary eat secondary. Producers (like plants) are the most plentiful.
Biogeochemical cycle depends on bacteria, what is it
Nitrogen-fixing bacteria and denitrifying bacteria are essential.
Water cycle undergoes percolation, 2 ways into atmosphere
Water enters the atmosphere through evaporation and transpiration.
Carbon in animal get into atmosphere? 2 ways
Through cellular respiration and decomposition.
Soil best near equator: forest, why true?
Equatorial regions have rich biodiversity and high decomposition rates, enriching the soil, but nutrient loss is rapid if the forest is removed.
What Makes loam
Sand, clay, silt
Forest cleared for farm: called?
slash-and-burn agriculture
What 3 components part of biodiversity conservation
Protect species
Preserve habitats
Maintain genetic diversity
Geothermal energy
Renewable energy from the Earth’s internal heat.
