Ecosystem Interactions and Competition

The video explores ecosystems, focusing on the interactions between organisms and their environment. It covers biotic and abiotic factors, how organisms depend on these factors, and the competition for resources. The video also discusses the impact of competition on populations and the adaptations organisms develop to reduce competition. Interactive elements and challenge questions are included to engage viewers and reinforce learning.

What is the primary focus of an ecosystem?

• The interaction between living organisms only

• The interaction between non-living elements only

• The balance between living and non-living factors

• The competition among predators

Which of the following is a biotic factor in an ecosystem?

• Water

• Temperature

• Bacteria

• Sunlight

How do abiotic factors influence organisms in an ecosystem?

• They determine the food chain

• They affect where organisms can live and reproduce

• They provide shelter for animals

• They are not important for survival

What is intraspecific competition?

• Competition between different species

• Competition within the same species

• Competition for abiotic factors

• Competition for sunlight

Why do plants compete for sunlight in a forest?

• To attract pollinators

• To store more water

• To grow taller than other plants

• To capture more light for photosynthesis

What role does competition play in population control?

• It leads to the extinction of all species

• It has no effect on population sizes

• It prevents overpopulation by allowing only the strongest to survive

• It increases the number of species

How do species reduce direct competition in an ecosystem?

• By occupying the same niche

• By adapting to different roles or niches

• By increasing their population size

• By migrating to other ecosystems

What is resource partitioning?

• Sharing resources equally among species

• Using resources in slightly different ways to reduce competition

• Eliminating weaker species

• Competing for the same resources

Why might nocturnal animals hunt at night?

• To conserve energy

• To avoid competition for water

• To avoid daytime predators

• To find more food

How do adaptations help organisms in an ecosystem?

• They increase competition

• They allow organisms to exploit different resources

• They decrease the number of species

• They have no effect on survival
