This hard outer covering helps animals like turtles and snails stay safe from predators.
What is a shell?
Birds flying south for winter is an example of this behavior.
What is migration?
This happens to populations when food supply decreases.
What is population decreases?
The main source of energy for most ecosystems is this.
What is the Sun?
When a species becomes a new species through adaptations
Evolution
A giraffe’s long neck allows it to do this for survival.
What is reach high leaves for food?
Bears sleeping through winter is called this.
What is hibernation?
When excess nutrients enter a water system, causing rapid algae growth that reduces oxygen for fish, this process is called this.
What is an algal bloom (or eutrophication)?
Plants use sunlight to make food through this process.
What is photosynthesis?
Group of organisms that look alike and can reproduce
Species
Webbed feet in ducks help them survive by improving this ability.
What is swimming?
Nocturnal animals are active during this time.
What is nighttime?
Removing a predator from an ecosystem can cause prey populations to do this.
What is increase?
Energy moves through an ecosystem in this structure.
What is a food chain (or food web)?
When humans burn fossil fuels, large amounts of carbon dioxide are released into the atmosphere, affecting this global system.
What is the carbon cycle?
Cactus spines are an adaptation that helps reduce this.
What is water loss?
Hunting in packs helps wolves do this more effectively.
What is catch prey/find food?
Pollution in water can negatively affect this in organisms.
What are life processes (or survival/health)?
Decomposers recycle this back into the ecosystem.
What are nutrients (or matter)?
A chicken’s comb and wattles help regulate this important body function.
What is body temperature?
Camouflage coloring helps organisms do this in their environment.
What is blend in/avoid predators?
A lizard basking in the sun is regulating this.
What is body temperature?
When large areas of forest are cleared for agriculture or development, animal populations often become smaller and more isolated. This environmental change is known as this.
What is habitat destruction?
When looking at a energy pyramid what percentage is heat (or lost energy)?
Only about 10% of energy is transferred from one trophic level to the next; the rest is lost as this.
Chickens roll in dirt to keep their feathers clean and remove parasites. This behavior is called this.
What is dust bathing?
