Ecosystem Dynamics and Energy Flow in Nature

The video explores the dynamics within ecosystems, focusing on food webs, energy flow, and the roles of producers, consumers, and decomposers. It delves into trophic levels, predator-prey relationships, and symbiotic interactions, highlighting their importance in maintaining ecological balance. The video concludes with a summary of these key concepts, encouraging viewers to stay curious about nature.

What is the primary role of producers in an ecosystem?

• To regulate predator populations

• To decompose organic matter

• To consume other organisms

• To produce energy through photosynthesis

What is the role of decomposers in a food web?

• To break down dead material

• To consume producers

• To hunt prey

• To produce energy

In a forest ecosystem, which organism is typically a consumer?

• Rabbits

• Fungi

• Plants

• Bacteria

How does energy flow in a food web?

• From predators to prey

• From consumers to producers

• From decomposers to producers

• From producers to consumers

What happens if there are too many predators in an ecosystem?

• The prey population increases

• The ecosystem becomes more balanced

• The ecosystem remains unchanged

• The prey population decreases

What is the effect of too few predators in an ecosystem?

• The predator population increases

• The ecosystem remains stable

• The ecosystem becomes unbalanced

• The prey population decreases

Which type of symbiotic interaction benefits both species involved?

• Predation

• Mutualism

• Commensalism

• Parasitism

In commensalism, how is the second species affected?

• It benefits

• It becomes a predator

• It is harmed

• It is unaffected
