Interactions Among Plants

What is plant competition and how does it affect growth?

• Plant competition only affects flowering plants.

• Plant competition enhances growth by providing more nutrients.

• Plant competition negatively affects growth by limiting access to essential resources.

• Plant competition has no impact on growth rates.

Name two types of resources that plants compete for.

• sunlight, water

• carbon dioxide

• nutrients

• soil type

How does allelopathy influence plant competition?

• Allelopathy has no effect on plant competition.

• Allelopathy only promotes the growth of all plants equally.

• Allelopathy is a physical competition for sunlight among plants.

• Allelopathy influences plant competition by allowing some plants to inhibit or promote the growth of others through chemical means.

What is mutualism in plants?

• Mutualism in plants is when plants grow independently without any interaction with other species.

• Mutualism in plants refers to a parasitic relationship where one plant harms another.

• Mutualism in plants is a symbiotic relationship where both plant species and their partners, like pollinators or mycorrhizal fungi, benefit from each other.

• Mutualism in plants is a competition between different species for resources.

Give an example of a mutualistic relationship involving plants.

• The relationship between plants and herbivores.

• The relationship between plants and soil nutrients.

• The relationship between plants and fungi that harm them.

• The relationship between flowering plants and bees.

How do mycorrhizal fungi benefit plants in a mutualistic relationship?

• Mycorrhizal fungi only benefit themselves without any gain for plants.

• Mycorrhizal fungi benefit plants by improving nutrient and water uptake while receiving carbohydrates in return.

• Mycorrhizal fungi provide plants with oxygen while taking in nitrogen.

• Mycorrhizal fungi harm plants by stealing nutrients and water.

What role do pollinators play in plant mutualism?

• Pollinators do not interact with plants at all.

• Pollinators harm plants by consuming their leaves.

• Pollinators only help plants grow taller without reproduction.

• Pollinators help plants reproduce by transferring pollen, while receiving food in return.

Explain how competition can lead to niche differentiation among plants.

• Niche differentiation occurs only in animal species.

• Plants thrive better in identical environments without competition.

• Competition has no effect on plant adaptation.

• Competition leads to niche differentiation among plants by driving them to adapt to specific environments and resources.

What is the significance of plant competition in ecosystem dynamics?

• Plant competition is significant as it influences species diversity, resource allocation, and ecosystem structure.

• Plant competition reduces the overall biomass of an ecosystem.

• Plant competition solely benefits invasive species.

• Plant competition has no impact on ecosystem health.

How can mutualism among plants enhance biodiversity?

• Mutualism enhances biodiversity by promoting species interactions that increase genetic diversity and ecosystem resilience.

• Mutualism reduces competition among plants, leading to fewer species.

• Mutualism among plants decreases genetic diversity and ecosystem stability.

• Mutualism only benefits individual species without affecting the ecosystem.
