Ecosystems Quiz

What is a food chain?

• A food chain is a linear sequence of organisms where each organism is the food source for the next organism in the sequence.

• A food chain is a sequence of organisms where each organism consumes the same type of food as the previous organism in the sequence.

• A food chain is a network of organisms where each organism consumes multiple food sources.

• A food chain is a circular sequence of organisms where each organism is the food source for the previous organism in the sequence.

Name the different trophic levels in a food chain.

• herbivores, carnivores, omnivores

• predators, prey, decomposers

• autotrophs, heterotrophs, detritivores

• producers, primary consumers, secondary consumers, and tertiary consumers

Explain the concept of energy transfer in a food chain.

• Energy transfer in a food chain is the process of energy being lost as heat during digestion.

• Energy transfer in a food chain is the process of energy being transferred through the air.

• Energy transfer in a food chain is the process of energy being passed from one organism to another through the consumption of food.

• Energy transfer in a food chain is the process of energy being created by the organisms themselves.

What is a biome?

• A biome is a term used to describe the study of animal behavior in their natural habitats.

• A biome is a large geographical area characterized by its distinctive climate, vegetation, and animal life.

• A biome is a man-made structure designed to house a specific type of vegetation and animal life.

• A biome is a small geographical area characterized by its distinctive climate, vegetation, and animal life.

List three major biomes found on Earth.

• Tundra biome

• Mountain biome

• Forest biome, Grassland biome, Desert biome

• Ocean biome

What factors determine the type of biome in a particular area?

• Vegetation, animal species, and human activity.

• Elevation, wind patterns, and sunlight exposure.

• Water availability, land use, and population density.

• Climate, temperature, precipitation, soil type, and topography.

Define biodiversity.

• Variety of life forms

• The study of ecosystems.

• Number of individuals in a population.

• Different species of organisms.

Why is biodiversity important for ecosystems?

• Biodiversity has no impact on the stability of ecosystems.

• Biodiversity ensures stability and resilience of ecosystems.

• Biodiversity increases the risk of disease outbreaks in ecosystems.

• Biodiversity leads to the depletion of natural resources in ecosystems.

What are the threats to biodiversity?

• Hunting, deforestation, and pollution.

• Habitat loss, pollution, climate change, overexploitation, and invasive species.

• Natural disasters, deforestation, and overpopulation.

• Deforestation, urbanization, and genetic modification.

How can we protect and conserve biodiversity?

• Implementing measures such as promoting urbanization in natural habitats, increasing pollution and waste, reducing awareness about the importance of biodiversity conservation, and allowing unrestricted exploitation of natural resources.

• Implementing measures such as hunting and fishing, promoting deforestation, increasing pollution and waste, and introducing more invasive species.

• Implementing measures such as reducing protected areas, promoting unsustainable land and water management practices, increasing pollution and waste, and ignoring the importance of biodiversity conservation.

• Implementing measures such as creating protected areas, promoting sustainable land and water management practices, reducing pollution and waste, controlling invasive species, and raising awareness about the importance of biodiversity conservation.
