Vocab 1
Animals who primarily eat plants
Herbivores
Animals who primarily eat meat
Carnivores
This will happen to the number of prey in an ecosystem if the number of predators increases
Decrease
This organism is the most important part of the energy pyramid/food web for transferring energy to other organisms.
Producers
organisms that eat both plants and animals
Omnivores
Grass → Mouse → Snake → Hawk
Which organism is the producer?
Grass
All the organisms in an area and the environment they live in
An ecosystem
Organisms that eat other animals and plants for energy
Consumers
This is what the arrows in a food chain represent
Energy transfer
This level of consumers are usually herbivores
Primary consumers
This is an example of a decomposer
Mushroom, worm, mold/fungus or bacteria
Grass → Mouse → Snake → Hawk
Which organism is the secondary consumer?
Snake
Organisms that produce or create their own food/energy
Producers
Process where plants take in water, carbon dioxide, and sunlight to produce energy and oxygen.
Photosynthesis
This is the difference between food chains and food webs
Food chains show energy transfer between single organisms while food webs show energy transfers between food chains (many of the organisms in an ecosystem)
This level of consumers are usually medium omnivores
Secondary consumers
These 2 items are what plants produce when they go through photosynthesis
Oxygen and energy (sugar)
Which organism is the primary consumer?
Mouse
The transfer of energy between single organisms
Food chain
Shows energy transfer between food chains
Food web
This is the reason decomposers are important to the ecosystem
They break down dead organisms which provides space and nutrients for new organisms to grow
This level of consumers is usually large carnivores/predators
Tertiary Consumers
Green pigment in leaves which allows plants to absorb sunlight for energy
Chlorophyll
Which organism is most essential for the survival of the rest of the organisms, without it the rest of the foodchain will die?
Grass
What PH level shows that water is neutral? (number)
7
Organisms that break down dead organisms to get their energy
Decomposers
This is what would happen to the food chain if the producer was wiped out or died
Each level of consumer from primary to tertiary would no longer have a food source and the food chain would collapse
This is how much energy is passed from one organism to another when it is eaten (as a percentage)
10%
These 3 things are needed for plants to take in in order to perform photosynthesis
Sunlight, water, and carbon dioxide
2 parts- Must get both parts correct
1. What classification of organism is responsible for recycling nutrients in the ecosystem?
2. What is the main source of energy for the entire ecosystem --> This starts where ALL organisms in the ecosystem get their energy
1. Decomposers
2. The Sun. The Sun gives energy through light to producers. No sun = no energy for producers. No producers = no ecosystem
