Ecosystems
What is an ecosystem?
An ecosystem is a community of living organisms interacting with their physical environment.
How do plants survive in deserts?
Plants survive in deserts by adapting features such as deep roots, water storage, and reduced leaf surface area.
What is climate?
Climate refers to the long-term weather patterns in a specific area.
Why is biodiversity important?
Biodiversity is important for ecosystem resilience, stability, and providing resources for food, medicine, and clean air.
Where are grasslands located?
Grasslands are found on every continent except Antarctica, often in regions with moderate rainfall.
Name a type of forest.
Examples: Tropical rainforest, deciduous forest, coniferous forest.
What is permafrost?
Permafrost is a permanently frozen layer of soil beneath the surface in tundra regions.
How does climate affect ecosystems?
Climate affects ecosystems by determining the types of vegetation and animal life that can thrive in a region.
What is a carnivore?
A carnivore is an animal that primarily eats other animals.
What continents have the most temperate grasslands?
North America, Europe, and parts of Asia have significant temperate grasslands.
What is the main idea of ecosystems?
The interaction of plant life, animal life, and the physical environment forms the earth’s many ecosystems.
Name an adaptation of desert animals.
Examples include nocturnal behavior, water conservation methods, and specialized diets.
Name a factor that affects life in an ecosystem.
Factors include temperature, precipitation, soil type, and availability of sunlight.
Name an example of a herbivore.
Examples include deer, rabbits, and elephants.
What is a chaparral ecosystem?
A chaparral ecosystem is characterized by hot, dry summers and mild, wet winters, with dense, drought-resistant shrubs.
How do ecosystems interact?
Ecosystems interact through food chains, nutrient cycling, and energy flow among organisms.
How do herbivores adapt to grasslands?
Herbivores adapt through grazing, migrating seasonally, and having digestive systems suited for grass.
What are temperate grasslands?
Temperate grasslands are characterized by moderate rainfall and are dominated by grasses, with few trees.
How do ecosystems support wildlife?
Ecosystems provide habitats, food sources, and breeding grounds for a variety of wildlife.
Describe the climate of a tropical rain forest.
Tropical rain forests have warm temperatures and high levels of rainfall year-round, supporting diverse plant and animal life.
Describe a tundra ecosystem.
A tundra ecosystem is characterized by cold temperatures, permafrost, and limited vegetation including mosses and lichens.
Explain the significance of the savanna.
Savannas are important for biodiversity and provide habitat for many species, including large herbivores and their predators.
How do seasons affect deciduous forests?
Seasons cause deciduous trees to shed leaves in the fall and regrow them in spring, affecting wildlife and plant cycles.
What threats do ecosystems face?
Threats include habitat destruction, climate change, pollution, and invasive species.
How does latitude affect ecosystems?
Latitude affects the amount of sunlight and temperature, influencing the types of ecosystems that can exist in different regions.
