Ecological Pyramids: Review

Front

What is an ecological pyramid?

Back

An ecological pyramid is a graphical representation that shows the relationship between different trophic levels in an ecosystem, illustrating the flow of energy or biomass.

Front

What are the three main types of ecological pyramids?

Back

The three main types of ecological pyramids are: 1. Pyramid of Numbers, 2. Pyramid of Biomass, 3. Pyramid of Energy.

Front

What is the role of producers in an ecological pyramid?

Back

Producers, such as plants, are at the base of the ecological pyramid and convert sunlight into energy through photosynthesis, forming the foundation of the food chain.

Front

What is the difference between primary consumers and secondary consumers?

Back

Primary consumers are herbivores that eat producers, while secondary consumers are carnivores that eat primary consumers.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth and maintains ecosystem health.

Front

How does energy flow through an ecological pyramid?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and so on, with energy decreasing at each trophic level due to energy loss as heat.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Front

What are the reactants and products of photosynthesis?

Back

Reactants: carbon dioxide and water; Products: glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What are the reactants in the equation for cellular respiration?

Back

The reactants in cellular respiration are glucose and oxygen.
