The Water Cycle
What is the water cycle?
The constant movement of water around an ecosystem
What part of a plant takes in water for photosynthesis?
The roots
What powers an ecosystem by giving it energy?
The sun
Which of these three things is a biotic factor: sunlight, a pond, or a flower?
A flower
Which of these three things is an abiotic factor: a berry, a rock, or a river?
A rock
What is evaporation?
Water evaporates (turns into gas) and rises into the air
What are stomata?
The microscopic holes on a plant that breathe in carbon dioxide and breathe out oxygen
How do herbivores get energy?
From eating plants
What is an omnivore?
An animal that eats both plants and animals
How can rainfall affect ecosystems?
Nourish plants/animals, create muddy/swamp conditions, create places for insects and animals to live, cause flooding
What is precipitation?
Rain
What two things do plants put out/create during photosynthesis?
Oxygen and glucose (sugar/energy)
How do carnivores get energy?
From eating other animals
What is an example of a decomposer?
Worms, bacteria, fungi
How can high temperatures affect ecosystems?
Plants may hibernate or die, water sources for animals may dry up, drought, wildfires
What happens during plant uptake?
Plants take water from the ground into their roots.
What three things do plants take in during photosynthesis?
Sunlight, water, and carbon dioxide
How do plants get energy?
From photosynthesis
Can an animal survive in the range of intolerance?
No, the range of intolerance is the conditions created by abiotic factors that a species cannot survive (for example, too low of a temperature that will make plants unable to grow)
What is the difference between dirt and soil?
Dirt is inorganic (dead) matter, while soil is organic (living) matter.
What happens during percolation?
Water from rainfall or runoff seeps into the ground.
What does it mean if a plant has more or less stomata?
They will produce more or less oxygen based on the amount of stomata.
What is energy?
Fuel/power for an ecosystem; it is how living things are able to move, grow, and do things
What is the zone of stress?
The conditions in an ecosystem that plants and animals can technically survive, but they will be "stressed out." For example, a berry bush that can survive higher temperatures, but will not produce berries when it is too hot.
What is the range of tolerance?
The range of an abiotic factor that a biotic factor can tolerate (live in): for example, the highest and lowest temperature a type of flower can survive in
