Describe the energy conversions that take place in a hair dryer. Electrical to kinetic, thermal and sound
Describe the energy conversions in a battery. Chemical into electrical
Describe what happens during photosynthesis. The plants use light energy to produce new substances with chemical energy.
What is the best definition of energy? Energy is the ability to do work.
What is a producer? Is the 1 st organism in a food chain
What is a herbivore? They eat only plants
What is an omnivore? They eat both (plants and animals).
What is a carnivore? They eat other animals.
What would happen if all the carnivores were removed from an ecosystem? The herbivore population would increase
Describe the correct energy transformations in a working toaster. Electrical to thermal
What type of energy do apples provide when they are eaten? Chemical energy
Food chain: Shows the flow of energy as each organism eats the one below it
Food Web: Shows that energy flows in many directions through an ecosystem.
Describe the energy conversions that takes place in a solar heating system used to warm up a building. Light energy to thermal energy
Examples of conversions from chemical energy to thermal energy –Food is digested to regulate body temperature. –Charcoal is burned in a barbeque pit. –Coal is burned to boil water.

Renewable Resources: Solar Water Wind Geothermal Biomass
Nonrenewable resources: –FOSSIL FUELS (FFCON) Coal Oil Natural Gas Nuclear Energy
The energy in coal can ultimately be traced to____. The sun
What percent of the United States energy use comes from fossil fuels? –About 80%
Nuclear energy: –Is generated when the nucleus of a radioactive element splits.
Trees are part of the renewable resources
Energy is ____ at the higher levels of the energy pyramid. lost
Energy flows from the grass to ________.
What is energy?. WHAT IS ENERGY? Energy is the ability to do work. Work is done when a force causes an object to move in the direction of the force. Work.
2.1 – Energy Flow in Ecosystems. Energy flow in ecosystems Biomass is the total mass of all living things in a given area. – Biomass can also refer to.
Energy Part I Notes on the different types of energy.
Energy Flow through a Food Chain. ENERGY FLOW Autotrophs vs. Heterotrophs
NONRENEWABLE AND RENEWABLE RESOURCES. HMMMM.... What do you think nonrenewable resources are? Break it down... Nonrenewable? Resource?
Ecology. What is Ecology? Ecology is the study of interactions among organisms and between organisms and their environment. Ecology is the study of interactions.

Energy Flow in Ecosystems 3.4. Energy Flow When an animal eats a plant, energy is transferred from plant to animal The same thing happens when an animal.
Energy Without energy nothing happens.. Energy does work! Work is done when objects are moved or heated. Energy is never used up it is simply converted.
