Biotic/Abiotic
A tree is an example of which type of factor in an ecosystem?
What is a biotic factor?
This organism type is always found at the bottom of an energy pyramid.
What is a producer?
Plants use this process to make their own food.
What is photosynthesis?
This biome receives the least amount of precipitation.
What is the desert?
In this food chain, which organism is the producer?
Grass → Rabbit → Fox
What is grass?
Sunlight, water, and temperature are examples of this type of factor.
What are abiotic factors?
About this percentage of energy is passed from one trophic level to the next.
What is 10%?
Plants take in this gas during photosynthesis.
What is carbon dioxide?
This biome is known for evergreen trees and cold winters.
What is the taiga?
In this food chain, which organism is the primary consumer?
Bushes → Deer → Coyote
What is the deer?
A drought causes plants to have less water available. Drought is an example of this.
What is a limiting factor?
As you move higher on an energy pyramid, the amount of available energy does this.
What is decreases?
This gas is released by plants during photosynthesis
What is oxygen?
This biome has extremely cold temperatures and very little precipitation, and is found near the poles.
What is the tundra?
A food web is made up of many interconnected ________.
What are food chains?
Competition for food, predators, and disease are examples of limiting factors in this category
What are biotic limiting factors?
A deer eats grass. The deer would be classified as this type of consumer.
What is a primary consumer?
Name two things a plant needs to carry out photosynthesis.
What are sunlight and carbon dioxide?
Water is also correct.
This biome has the greatest biodiversity of all the biomes.
What is the rainforest?
Consider this food chain:
Bushes → Mouse → Snake → Hawk
If the mouse population suddenly decreased, which organism would most likely have less food available?
What is the snake?
A population can only grow until it reaches the maximum number of organisms an environment can support. This is called its ________.
What is carrying capacity?
If plants have 10,000 units of energy, approximately how much energy would be available to the primary consumers?
What is 1,000 units of energy?
Put these parts of photosynthesis in the correct relationship:
Sunlight + Carbon Dioxide + Water → ?
What is glucose + oxygen?
A biome is experiencing a long period with very little rainfall. Which biome would be best adapted to these conditions?
What is the desert?
Consider these food chains:
What type of diagram could combine all of these relationships into one model?
What is a food web?
