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?
While they share high precipitation, temperate rainforests are differentiated from tropicals ones primarily by this major climate factor
What is the cooler climate?
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?
Characterized by hot, dry summers and cool, wet winters, this coastal biome's plant life has adapted to survive frequent wildfires
In this food chain, which organism is the secondary consumer?
Bushes → Deer → Coyote
What is the coyote?
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 high-altitude biome has similar conditions found in polar regions, preventing tree growth due to win, permafrost and cold.
What is the alpine 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 covers almost 20% of the Earth's surface and has extreme temperature swings, defined by scarcity of moisture more than temperature
What is the desert?
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 secondary consumers?
What is 100 units of energy?
Put these parts of photosynthesis in the correct relationship:
Sunlight + Carbon Dioxide + Water → ?
What is glucose + oxygen?
Covering almost 6% of Earth's total land area, this has almost 50% of the total specials and relies heavily on moisture?
What is the tropical rainforest?
Consider these food chains:
What type of diagram could combine all of these relationships into one model?
What is a food web?
