Ecology Biosphere

How do biomes influence the organisms living in them?

• By providing specific environmental conditions

• By influencing the genetic makeup of the organisms

• By determining the political structure of the region

• By providing unlimited resources to the organisms

Explain the concept of ecological succession in biomes.

• Ecological succession is the process of creating artificial biomes in controlled environments.

• Ecological succession is the process of change in the weather patterns of a biome.

• Ecological succession refers to the migration of animals between different biomes.

• Ecological succession is the process of change in the species structure of an ecological community over time.

Explain the concept of a food web and its significance in an ecosystem.

• A food web is a diagram used to plan out meals for a week, showing the different food groups and their recommended servings.

• A food web is a type of spider web made from food items, commonly found in the Amazon rainforest.

• A food web is a type of internet connection specifically designed for ordering food online.

• A food web is a network of interconnected food chains, showing the flow of energy and nutrients through an ecosystem. It includes producers, consumers, and decomposers, and illustrates the complex relationships between different organisms.

What are the primary producers in a food web and their role?

• Organisms that produce their own food through photosynthesis or chemosynthesis

• Animals that hunt and consume other organisms

• Microorganisms that break down dead organic matter

• Plants that rely on consuming other organisms for food

How do changes in one population in a food web affect other populations?

• Changes in one population can only affect other populations if they are closely related genetically

• Changes in one population can affect other populations through direct and indirect interactions in the food web.

• Changes in one population only affect the population directly above it in the food web

• Changes in one population have no impact on other populations

What is an energy pyramid and how does it represent the flow of energy in an ecosystem?

• It represents the flow of energy in an ecosystem by showing the transfer of energy from one trophic level to another, with the highest energy level at the bottom and the lowest at the top.

• It represents the flow of energy in an ecosystem by showing the transfer of water from one trophic level to another, with the highest water level at the bottom and the lowest at the top.

• It represents the flow of energy in an ecosystem by showing the transfer of nutrients from one trophic level to another, with the highest nutrient level at the bottom and the lowest at the top.

• It represents the flow of energy in an ecosystem by showing the transfer of carbon dioxide from one trophic level to another, with the highest carbon dioxide level at the bottom and the lowest at the top.

Explain the concept of biomass in relation to energy pyramids.

• Biomass is the representation of the number of predators in an energy pyramid

• Biomass is the total number of organisms in an ecosystem

• Biomass represents the amount of energy available at each trophic level in an energy pyramid.

• Biomass is the measure of the amount of water in an ecosystem

What is a food chain? Explain with an example.

• A food chain is a type of necklace made from different types of food

• A food chain is a type of restaurant that specializes in serving only one type of food

• A food chain is a series of organisms each dependent on the next as a source of food.

• A food chain is a system of grocery stores that are all owned by the same company

Explain the concept of energy flow in a food chain.

• The exchange of energy between predators and prey in a food chain

• The process of water flowing through the food chain

• The transfer of energy from one organism to another through the consumption of food.

• The movement of energy from the sun to the plants in a food chain
