What is genetic diversity?

• Variety of ecosystems in a specific area
• The number of species in a region
• Types of habitats found worldwide
• Differences in characteristics among individuals

Why is genetic variability essential?

• It leads to habitat modification
• It prevents inbreeding and extinction
• It helps in developing crops
• It increases the number of species

What constitutes species diversity?

• The health of a breeding population
• The genetic differences among species
• The number of individuals in a species
• The variety of species in a region

Which ecosystems are typically richer in species?

• Intensive agricultural areas
• Urban modified areas
• Farmlands with single crops
• Natural undisturbed forests

What is ecosystem diversity?

• The differences in genetic makeup of individuals
• The variety of different ecosystems on Earth
• The adaptation of species to their habitats
• The number of species in agricultural systems

Which of the following is a characteristic of a natural ecosystem?

• It is primarily for agricultural use
• It consists of urban developments
• It is heavily modified by humans
• It has a high level of biodiversity

What happens when the number of breeding individuals is reduced?

• Genetic diversity increases significantly
• Species diversity becomes richer
• Inbreeding may occur, leading to problems
• Ecosystem diversity is enhanced

Which of the following is an example of an aquatic ecosystem?

• Deserts
• Grasslands
• Forests
• Rivers

What is a gene pool?

• The variety of ecosystems in an area
• The number of habitats available for species
• The total number of species in a region
• The genetic diversity available from wild species
