Question

elk__ shrub gray wolf grass moose__ 10. describe the flow of energy in the diagram above. (1pt) 11. what is the ultimate source of energy? (1pt) 12. define the following types of consumers (1pt). herbivores-...... carnivores-...... omnivores-...... decomposers-...... 13. define trophic levels (1pt)

Explanation:

1. Energy flows from the producer (grass) to the primary - consumer (grasshopper), then to the secondary - consumer (mouse), and finally to the tertiary - consumer (owl). This is a unidirectional flow of energy in the food chain.
2. The sun is the ultimate source of energy for most ecosystems. Through photosynthesis, plants convert solar energy into chemical energy, which then moves through the food chain.

12.

• Herbivores: Organisms that eat only plants.
• Carnivores: Organisms that eat other animals.
• Omnivores: Organisms that eat both plants and animals.
• Decomposers: Organisms that break down dead or decaying matter, recycling nutrients back into the ecosystem.

1. Trophic levels are the hierarchical levels in an ecosystem, each representing a different position in the food chain. Producers form the first level, followed by primary consumers, secondary consumers, and so on.

Answer:

1. Energy flows from grass (producer) to grasshopper (primary - consumer), to mouse (secondary - consumer), and to owl (tertiary - consumer).
2. The sun.

12.

• Herbivores: Organisms that consume plants.
• Carnivores: Organisms that consume other animals.
• Omnivores: Organisms that consume both plants and animals.
• Decomposers: Organisms that break down dead organic matter.

1. Hierarchical levels in an ecosystem representing different positions in the food chain.
