100
Any resource that restricts growth of populations.
What is a LIMITING FACTOR?
100
An animal that hunts other animals for food.
What is a PREDATOR?
200
The source of all energy for food chains and webs.
What is the SUN?
200
Made up of many populations in an ecosystem.
What is a COMMUNITY?
200
When a chimpanzee uses a stick to collect termites to eat, this is an example of a type of adaptation...behavioral or structural.
What is BEHAVIORAL?
200
The greatest number of individuals within a population that can survive in an ecosystem.
What is the CARRYING CAPACITY?
200
An example of an adaptation used by plants to protect from predators.
What is THORNS, or TOXIC CHEMICALS, or BAD TASTE?
300
A network of food chains that have some links in common.
What is a FOOD WEB?
300
This group is the largest in the energy pyramid.
What is the PRODUCERS?
300
A type of camouflage demonstrated by a tiger's stripes making it difficult to see in the grass.
What is PROTECTIVE COLORATION?
300
Overcrowding demonstrates this limiting factor.
What is SPACE (or an organism's need for space)?
300
This type of animal is helped by living on or in its host...the host is usually harmed.
What is a PARASITE?
400
Arrows in food chains and webs always point in this direction.
What is TOWARD THE HIGHER CONSUMER (in other words they point towards the one that eats)?
400
90% of the available energy at each level of the energy pyramid is lost as this.
What is HEAT?
400
The type of adaptation demonstrated by a snapping turtle wagging a lure under his tongue that looks like a worm.
What is MIMICRY?
400
A relationship between two or more kinds of organisms that lasts over time.
What is SYMBIOSIS?
400
An example of mutualism.
What is CLOWNFISH & ANEMONE, or OXPECKER BIRDS & RHINOS, or CLEANING FISH & LARGE REEF FISH, or other sensible symbiosis where both organisms are helped.

In the following food chain, name the type of organism each is: clover, rabbit, snake, hawk.
What is PRODUCER, PRIMARY CONSUMER (herbivore), SECONDARY CONSUMER (carnivore), TOP CARNIVORE/PREDATOR?
500
A land ecosystem has an energy pyramid. The producers have 1000 energy units. This is the amount of energy units given to the HERBIVORES and CARNIVORES.
What is 100 to the HERBIVORES and 10 to the CARNIVORES?
500
3 structural adaptations for surviving cold, snowy winters.
What is BODY FAT, WHITE COLOR, THICK FUR. (also accept black skin under the white fur--polar bears)
500
An example of this kind of symbiosis is rain forest orchids--they grow well high in a tree and do no harm to the tree.
What is COMMENSALISM?
500
The benefit of adaptations to a single organism and its offspring.
What is ORGANISM SURVIVAL AND PASSING HELPFUL TRAITS TO OFFSPRING AND FUTURE GENERATIONS. (Must have both parts of answer for full credit!)
