Glucose (or sugar/food) and oxygen
An organism that makes it own food.
Producer
An animal that only eats other animals
Carnivore
Invasive species have a __________ impact on ecosystems.
Negative
Bacteria, Fungi, and Insects are examples of:
Decomposers
The original source of energy for all organisms.
The sun.
The process by which light energy from the sun is converted into food.
Photosynthesis
Animals that eat both plants and animals.
Omnivore
Humans
Which of the following is a biotic factor? wind, tree leaves, small rocks, light from the sun
Tree leaves
A special cell found in a plant leaf that is responsible for trapping sunlight during photosynthesis.
Chloroplast
What three things do plants need for growth and survival?
CO2, Water, and Sunlight
A combination of several food chains is known as a ....
Food Web
Humans destroy ecosystems by ____________.
Overhunting, overfishing, habitat destruction, pollution
What do the arrows in a food chain or food web represent?
Transfer of energy
A network of overlapping food chains.
A food web.
What in the air do plants require for photosynthesis?
Carbon dioxide
A living organism that eats other living organisms is known as...
A consumer
A community of interacting organisms.
An ecosystem
Herbivores, carnivores, and omnivores are all types of:
Consumers
Recite a "mirror/mirror" for the steps of photosynthesis.
1. The sun hits the leaves
2. The leaves absorb sunlight
3.The stomata suck in CO2
4.The roots pull up water from the soil
5. The plant makes food/glucose
6. The stomata release O2
What is the main purpose of the roots and stem of a plant?
Roots- to suck up water from the soil and anchor the plant in place
Stem- to hold the plant upright
Create a food chain listing these organisms in order: mouse, snake, hawk, acorns
acorns --> mouse --> snake --> hawk
Humans can help repair the environment by...
Planting trees to help with erosion, not pollute, use water wisely, minimize development
Describe the chain of evens that would occur if the sun were blocked out for several months.
The plants would start dying because they couldn't photosynthesize, then herbivores would die without the plants as well as the omnivores and carnivores. The entire Food Web would collapse.
