Abiotic vs. Biotic
Is a rock abiotic or biotic?
Abiotic
Which biome is known for having the most biodiversity?
Rainforest
What type of organism makes its own food using sunlight or chemicals?
Producer
What is a small ecosystem, like a puddle or a patch of moss, called?
Micro-ecosystem
What is the primary source of energy for most food chains?
The Sun
Name one example of a biotic factor in a desert.
Examples include cactus, snake, lizard, etc.
Name a biome with very little rainfall and extreme temperatures.
What do we call animals that eat both plants and other animals?
Omnivores
What kind of ecosystem would you find in an ocean?
Saltwater ecosystem or Aquatic ecosystem
What would happen to consumers if all the producers in an ecosystem died?
Consumers would run out of food and eventually die.
How do abiotic factors like sunlight and water help biotic factors survive?
They provide energy, hydration, and resources for growth and survival.
Which biome has long, cold winters and is home to animals like caribou and wolves?
Tundra
Which role in the food chain breaks down dead plants and animals to return nutrients to the soil?
Decomposer
How is a macro-ecosystem different from a micro-ecosystem?
A macro-ecosystem covers a large area, like a forest or lake.
In a food chain, which level would a lion most likely belong to: producer, primary consumer, or secondary consumer?
Secondary consumer
What would happen to biotic factors if an important abiotic factor, like water, disappeared from an ecosystem?
Many living things would die or leave the area.
What are the two main factors that determine a biome?
Climate and geography
Why are decomposers important to ecosystems?
They recycle nutrients, keeping the ecosystem healthy
Name an example of a freshwater ecosystem.
Rivers, ponds, streams, lakes, etc.
How do producers, consumers, and decomposers work together to keep an ecosystem balanced?
Producers make food, consumers eat producers/other consumers, and decomposers recycle nutrients back into the ecosystem.)
Name two abiotic factors and explain how they work together to support life in an ecosystem.
Examples include sunlight and water—sunlight helps plants grow, and water is essential for hydration and nutrient absorption
Which biome has four distinct seasons and trees that lose their leaves in the fall?
Temperate forest/deciduous forest
In an aquatic ecosystem, which type of organism is usually the producer?
Algae or phytoplankton
What type of ecosystem can you find in a forest that includes trees, animals, and a river?
Terrestrial ecosystem
If a disease wipes out a population of primary consumers, how would it affect the producers and secondary consumers in the ecosystem?
Producers might overgrow due to less being eaten, while secondary consumers might struggle to find enough food and decline in number.
