Energy
What is the difference between potential energy and kinetic energy?
What is the difference between a producer and a consumer?
Producers make their own food (plants.) Consumers do not make their own food; they must consume other organisms for food (animals.)
Bees get pollen and nectar from flowers, which they spread to their colonies. Bees pollinate flowers, which allow them to reproduce. What type of symbiosis is this?
Mutualism - both organisms benefit
These two dry biomes are characterized by very little precipitation. One has a very hot climate, while the other has an extremely cold climate. Which two biomes are we?
Desert - Hot/Dry
Tundra - Cold/Dry
What makes something a natural resource?
1) If it comes from the Earth.
2) If humans use it.
Mechanical Energy
What are the three types of consumers?
Herbivore - eat only plants
Omnivore - eat plants and meat
Carnivore - eat only meat
Great White Sharks hunt seals for food. What type of relationship is this?
Predator - Prey
We live in this biome. It is categorized by having all four seasons that many types of animals and plant life can survive in.
Deciduous Forest
What is the difference between renewable resources and nonrenewable resources?
Renewable Resources are made as quickly as we use them, and can be used again and again.
Nonrenewable Resources cannot be made as quickly as we use them and take millions of years to form.
What does the Law of Conservation of Energy state?
Energy cannot be created or destroyed - only transformed.
Jaylin says that producers go at the top of the energy pyramid, because they make their own food. Is he correct or incorrect?
Lice live in human hair and feed off the blood of their host. Humans with lice experience itchy scalps and hair. What type of symbiotic relationship is this?
Parasitism - one organism benefits, one is harmed
About 3% of the water on Earth is this. This type of water is potable, or safe for drinking.
Freshwater
Why is polluted water that's been filtered still not as good as clean filtered water?
Filtered water cannot block all the pollutants - only some.
You are standing on top of a diving board, and then you jump into a pool. What kind of energy transformation has taken place?
Potential --> Kinetic
Where can all energy in a food web / food chain / energy pyramid be traced back to?
The Sun
What would happen if you removed one organism from the ecosystem?
The entire ecosystem would fall apart because organisms would die out one by one.
This type of aquatic biome is a mix of freshwater and saltwater. It is often located on or near a coastline.
Estuary
What are aquifers and why do we need to conserve how much of them we use?
Aquifers are sources of clean freshwater that can be used for agriculture and producing crops. We use them at a faster rate than they can be replaced.
What are the three types of thermal energy?
Radiation - the transfer of energy through electromagnetic waves
Conduction - the transfer of energy through materials/solids
Convection - the transfer of energy through liquids/gas
How could wildfire affect the food web?
Organisms may die out or seek other ecosystems for shelter, leaving their predators to slowly die out.
The remora fish can attach itself to a shark, whale, or large turtle and be carried from meal to meal, feeding on scraps scattered by its host. The remora neither harms nor helps the host. What type of symbiotic relationship is this an example of?
Commensalism - one organism benefits, the other is unharmed or unaffected
1. The recyclable items will go to the ocean where they take decades or centuries to break down.
2. Fish and sea life will ingest microplastics that can harm them and eventually end up in our food.
