Ecosystem
What is an ecosystem?
What are the 3 essential things all plants need?
Air, water, and sunlight
What does the food web show?
The foodweb shows how animals get energy in an ecosystem.
What are 3 types of matter you find in soil?
Dirt, dead matter/decomposers, water, sticks, rocks, nutrients
How do plants get their energy to start photosynthesis?
Plants get energy from the sun
T/F: A tree that has been struck down by lighting is an example of an ecosystem
True
T/F: Plants don't need soil to survive
How do animals grow?
Animals grow by gaining matter.
What are nutrients and why are they important?
Nutrients are like vitamins for plants. They help plants grow and thrive.
Which organism in a food web is considered a producer?
A green plant making its own food
What is in every ecosystem?
List 2 decomposers in an ecosystem
Earthworms, mushrooms, or planktons
What happens to the food animals eat?
Animals use thier food to move and grow
Can soil be different in different places? Explain an example.
What happens to energy as it moves through a food web?
It transfers from one organism to the next
Decomposers are important to an ecosystem because they help add nutrients in to the soil
Which plant would grow more:
1. A plant that has been in a dark room, but has water, carbon dioxide, and soil.
2. A plant that has been in the backyard and gets air, water, and carbon dioxide
Plant 2
What does every food web need to thrive?
How do decomposers help maintain healthy soil?
They break down dead organisms into nutrients
What is the difference between a producer and consumer? How do they each get energy?
A produces makes its own food (like a plant) and a consumer gets its energy from other organisms (by eating plants and animals).
What is an organism?
Any living thing
Photosynthesis is the process plants use to make their own food using sunlight, water, and carbon dioxide. They turn these ingredients into sugar for energy and release oxygen into the air.
Explain produces and consumers in an ecosystem
Producers are living things, like plants and algae, that make their own food using sunlight through photosynthesis.
Consumers are animals that cannot make their own food, so they eat plants or other animals to get energy. T
What happens when soil lacks proper nutrients?
Plants become weak and may die
What is an example of a consumer in a food web?
Any animal (humans, mouse, snake, rabbit)
