Quiz on Organisms and Environment

What is the broad descriptive grouping of living organisms based on?

• Size and color

• Plants and animals

• Habitat and diet

• Age and gender

Why is there a need for a scientific system for the classification of organisms?

• To make it easier to remember names

• To identify organisms and avoid common names

• To reduce the number of species

• To increase the population of species

What adaptations enable organisms to survive in their environment?

• Morphological and behavioral adaptations

• Physical and chemical adaptations

• Genetic and environmental adaptations

• Structural and functional adaptations

What resources do individual organisms need from their environment?

• Food, water, light, and minerals

• Shelter, mates, and territory

• Air, soil, and temperature

• Space, nutrients, and predators

What is the term used to describe the variety of different species and numbers of individuals within those species in an area?

• Ecology

• Biodiversity

• Population

• Community

Why is biodiversity important?

• It increases the number of predators

• It helps in the survival of species

• It reduces the need for resources

• It decreases the population size

What can be used to investigate the abundance of species?

• Microscopes

• Quadrats

• Telescopes

• Thermometers

What is the principle of sampling in ecological studies?

• To collect sufficient data

• To reduce the number of species

• To increase the population size

• To eliminate predators

What technique involves simple calculations on estimated population size?

• Sampling

• Capture/recapture

• Quadrating

• Tagging

What are the possible issues surrounding the use of biological control agents?

• They can increase the population size

• They can introduce alien species

• They can reduce biodiversity

• They can eliminate all predators
