Biotic and Abiotic Factors

How do abiotic factors affect biodiversity?

• Abiotic factors have no effect on biodiversity.

• Abiotic factors like climate and soil type can influence the variety of species that can thrive in an ecosystem.

• Abiotic factors only affect the physical appearance of species.

• Abiotic factors are irrelevant to ecosystem health.

What is a biotic factor?

• A non-living component of an ecosystem, such as rocks and water.

• A living component of an ecosystem, such as plants, animals, and microorganisms.

• A chemical substance that affects living organisms.

• A physical feature of the environment, such as temperature and sunlight.

Name three biotic factors.

• Birds, trees, and insects

• Rocks, water, and sunlight

• Clouds, air, and temperature

• Plastic, metal, and glass

What is an abiotic factor?

• A living organism in an ecosystem

• A non-living component of an ecosystem, such as temperature, water, sunlight, and soil.

• A type of biotic interaction between species

• A measure of biodiversity in an ecosystem.

What is the importance of sunlight in an ecosystem?

• It provides energy for photosynthesis, which is essential for plant growth.

• It helps in the formation of soil by breaking down rocks.

• It regulates the temperature of the ecosystem.

• It is a source of water for plants.

Give an example of an abiotic factor.

• Temperature

• Bacteria

• Fungi

• Plants

How do biotic and abiotic factors interact?

• Biotic factors are independent of abiotic factors and do not require them for survival.

• Biotic factors depend on abiotic factors for survival; for example, plants (biotic) need sunlight and water (abiotic) to grow.

• Abiotic factors are the primary determinants of biotic factors, with no interaction between them.

• Biotic factors can thrive in any abiotic condition without any specific requirements.

What is an example of a biotic interaction?

• Predation, where carnivores consume other animals, is an example of a biotic interaction.

• Photosynthesis, where plants convert sunlight into energy, is an example of a biotic interaction.

• Decomposition, where fungi break down dead organic matter, is an example of a biotic interaction.

• Pollination, where insects transfer pollen between flowers, is an example of a biotic interaction.

Why are decomposers considered biotic factors?

• They produce energy through photosynthesis.

• They break down dead organic matter, recycling nutrients back into the ecosystem.

• They are non-living components of the environment.

• They compete with plants for sunlight.

Name three abiotic factors.

• Water, sunlight, and air

• Soil, temperature, and plants

• Water, sunlight, and soil

• Air, rocks, and trees
