Ecological Hierarchy

What is the lowest level of ecological hierarchy?

• Ecosystem level

• Individual organism

• Population level

• Community level

Name the levels of ecological hierarchy in ascending order.

• individual, population, community, ecosystem, biome, biosphere

• family, city, country, continent, planet

• cell, tissue, organ, organ system, organism

• producer, primary consumer, secondary consumer, tertiary consumer, decomposer

Give an example of a population in an ecological hierarchy.

• A population of fish in a desert ecosystem.

• Example: A population of deer in a forest ecosystem.

• A population of birds in a marine ecosystem.

• A population of insects in a tundra ecosystem.

Explain the concept of community in ecological hierarchy.

• A community in ecological hierarchy refers to all the populations of different species that live and interact in the same area, representing the various relationships and interactions between different species within a specific ecosystem.

• A community in ecological hierarchy refers to a single species dominating an entire ecosystem

• A community in ecological hierarchy refers to the physical environment of an ecosystem

• A community in ecological hierarchy refers to the interactions between different ecosystems

How does an ecosystem differ from a biome in ecological hierarchy?

• An ecosystem focuses on the interactions between living organisms and their environment, while a biome focuses on the physical and climatic characteristics of a large geographical area.

• An ecosystem is always located within a biome

• An ecosystem only includes plants and animals, while a biome includes all living organisms

• An ecosystem is smaller in size compared to a biome

What is the role of a keystone species in ecological hierarchy?

• The role of a keystone species is to have no impact on the ecological community

• The role of a keystone species is to only influence a single species in the ecological community

• The role of a keystone species is to have a significant influence on the composition and diversity of the ecological community, often by controlling the population of other species or shaping the physical environment.

• The role of a keystone species is to always cause harm to the ecological community

Describe the concept of a food chain in ecological hierarchy.

• A food chain is a circular sequence of organisms where each organism eats the next one and is eaten by the previous one, showing the flow of energy and nutrients through an ecosystem.

• A food chain is a hierarchy of organisms where each organism eats all the others and is eaten by all the others, showing the flow of energy and nutrients through an ecosystem.

• A food chain is a linear sequence of organisms where each organism eats the previous one and is eaten by the next one, showing the flow of energy and nutrients through an ecosystem.

• A food chain is a random sequence of organisms where each organism eats any other organism and is eaten by any other organism, showing the flow of energy and nutrients through an ecosystem.

What are the major components of a food web in ecological hierarchy?

• Producers, consumers, and decomposers

• Predators, prey, and scavengers

• Plants, animals, and minerals

• Herbivores, carnivores, and omnivores

Explain the concept of a trophic level in ecological hierarchy.

• A trophic level is a measure of an organism's physical size within an ecosystem

• A trophic level is a classification system for organisms based on their genetic makeup

• A trophic level is a position in the food chain or energy pyramid, representing the different levels of organisms that consume or produce energy.

• A trophic level is a term used to describe the geographical location of an organism within an ecosystem

Discuss the importance of biodiversity in ecological hierarchy.

• Biodiversity has no impact on ecological hierarchy

• Ecosystems are more stable with less biodiversity

• Ecosystem services are not affected by biodiversity

• Biodiversity is important in ecological hierarchy because it contributes to the stability and resilience of ecosystems and provides various ecosystem services.
