Key Concepts in Ecology

• Biomass Pyramid

  • Levels: Primary Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers

  • Example:

  • Primary Producers (e.g., plants)

  • Primary Consumers: Herbivores

  • Secondary Consumers: Carnivores or Omnivores (e.g., snakes)

  • Tertiary Consumers: Carnivores (e.g., hawks)

• Food Chain and Food Web

  • Importance: Understand the flow of energy and nutrients through an ecosystem

  • Create diagrams to illustrate these concepts

• Trophic Levels

  • Define: Position of an organism in the food chain

  • Example: Primary producers = 1st trophic level, etc.

• Carrying Capacity

  • Definition: Maximum number of organisms an ecosystem can support

• Questions to Review

  • Be prepared for short answer questions based on reading passages, focusing on claims, evidence, and reasoning (CER)

• Helpful Hints

  • Familiarize with all zo forms (likely refers to biological forms)

  • Understand the different parts and examples of biomass pyramids and their significance in ecosystems.
