Biology Quiz: Plant Structure and Ecosystem

Plant Structure and Function

• Xylem tissues carry water from the roots through the stem.
• Phloem tissues do not carry water from the roots through the stem.

Ecosystems and Producers

• Grass is an example of a producer in an ecosystem.
• Producers make their own food through photosynthesis.

Stomata Function

• Stomata are responsible for carrying out gas exchange in plants.

Invasive Species

• Invasive species are not native to an ecosystem.
• Invasive species can harm the environment, spread quickly, and damage the economy and human health.

Niche and Habitat

• An earthworm's niche is breaking down plant matter in the soil.
• Habitat refers to the natural environment in which an organism lives.

Plant Leaves and Nutrients

• Leaves take in sunlight and carbon dioxide to obtain nutrients for the plant's survival.
• Leaves do not take in water and give off carbon dioxide.

Plant Growth Conditions

• Plants need soil and water to grow and survive.
• Plants can be affected differently by various growing conditions.

Hydrosphere Interaction

• Interacting with the hydrosphere can be done through activities like swimming.

Ecosystem Matter Transfer

• Matter transfers among organisms and the ecosystem.

Food Chain and Predation

• Prey refers to organisms that are eaten by other animals.
• Herbivores, carnivores, and predators have distinct roles in the food chain.

Decomposers and Ecosystem Balance

• Decomposers break down plant and animal matter, maintaining ecosystem balance.
• Decomposers enrich the soil, helping plants grow.

Earth's Systems

• The geosphere, hydrosphere, atmosphere, and biosphere are interconnected Earth systems.
• Rivers are part of the hydrosphere, not the geosphere.

Desert Ecosystem Interactions

• In a desert ecosystem, the geosphere and hydrosphere interact with each other.

Water Cycle

• Condensation is the process of water vapor changing to a liquid.
