Energy Pyramid
The term for the organisms found at the base of an energy pyramid
Producers
The process by which plants convert sunlight into chemical energy
Photosynthesis
A linear sequence of organisms, where each serves as a source of food for the next
Food Chain
The term for an organism that eats both plants and animals
Omnivore
The Law of Conservation of Energy
Energy cannot be created or destroyed
Percentage of energy is typically lost as heat between trophic levels in an energy pyramid
90%
During photosynthesis, this gas is taken in from the atmosphere
CO2 or Carbon Dioxide
The term for an organism that primarily feeds on plants in a food chain
herbivore
The role decomposers play in an ecosystem
Removal of dead matter
The difference between a food web and the energy pyramid
Food webs are many interconnected food chains, energy pyramids are diagrams showing the decrease in energy as it passed through the levels
This trophic level consists primarily of organisms that feed on producers
Primary Consumers or Herbivores
This organelle in plant cells is responsible for photosynthesis
Chloroplast
A complex network of interconnected food chains, illustrating multiple feeding relationships in an ecosystem
Food Web
An organism that feeds on primary consumers; typically carnivores or omnivores
Secondary Consumer
The 10% rule
Only 10% of energy is passed up the pyramid per level, 90% is lost as heat and waste
The term describes organisms at the highest trophic level in an ecosystem
apex consumer
The primary molecule produced by photosynthesis that stores chemical energy
Glucose
In a food chain this is the primary source of energy
The Sun
An organism that feeds directly on producers; also known as herbivores
primary consumer
What happens to an ecosystem if the producers are lost
The entire ecosystem will collapse
This type of organisms play a vital role in breaking down organic matter and recycling nutrients in an ecosystem
Decomposer
During photosynthesis, this gas is released into the atmosphere
Oxygen
the difference between a food chain and a food web
Food webs are interconnected food chains
The chemical process by which radiant energy, H2O and CO2 are turned into C6H12)6 and O2 (and heat)
Photosynthesis
Which is more likely to survive losing a member (producer, consumer)?
Food Web
