• only the nonliving things in the environment

• how living things interact with each other and the nonliving things in the environment

• scientists who perform research on living things

Multiple Choice

Multiple Choice

Where an organism lives

• habitat
• niche 
• heterotrogh
• biosphere

Multiple Choice

What would be a hawkbill's habitat?

• Where it lives

• What it eats

• When it migrates

Multiple Choice

What is a niche?

• The habitat that an organism lives in

• An organism’s “role” in an ecosystem

• A type of consumer

• The relationship between a producer and consumer

Multiple Choice

What happens when different species try to occupy the same niche?

• The species compete with each other

• The species cooperate with each other

• The species coexist with each other

• All of the above

Multiple Choice

The total number of individuals a habitat can survive with the resources it has available.

• Carrying capacity
• Limiting factors
• Resources
• Population

Multiple Choice

What is a limiting factor?

• Factors that always increase a population

• Factors that always decrease a population

• Resources that are unlimited

• Factors/resources that limit how many organisms can live in an area at the same time

Multiple Choice

If there was a wildfire in the forest that destroyed the plant life, what would happen to the herbivore population?

• Herbivores would decrease due to a lack of food

• Herbivores would increase due to an increase of food

• Herbivores would not be affected

• Herbivores would decrease due to an increase in predators

Multiple Choice

What type of organism can make its own food?

• A producer (an autotroph)

• A consumer (a heterotroph)

• A decomposer

• All of the above

Multiple Choice

Organisms that can make their own food do so by the process of:

• decomposition

• respiration

• photosynthesis

• scavenging

Multiple Choice

The first organism in a food chain is ALWAYS a:

• producer

• consumer

• decomposer

• Any of the above

Multiple Choice

Organisms that relies on other organisms for food; consumer

• herbivore
• decomposer
• heterotroph
• species

Multiple Choice

An organism that needs to eat other organisms to obtain energy is known as a:

• Autotroph
• Producer
• Consumer
• Mutualist

Multiple Choice

What type of consumer eats plants?

• Herbivore

• Omnivore

• Carnivore

• Both herbivore and omnivore

Multiple Choice

How does oxygen cycle between plants and animals?

• Plants and animals both release oxygen

• Plants and animals convert water into oxygen

• Plants take in oxygen that is produced by animals

• Animals take in oxygen that is produced by plants

Multiple Choice

• Endangered

• Specialists

• Extinct

• Generalists

Multiple Choice

These animals have specific diet and climate requirements

• Extinct

• Generalists

• Specialists

• Endangered

Multiple Choice

Organisms adapted to narrow habitats, limited food resources, or other specific environmental conditions.

• Specialist

• Generalist

Multiple Choice

In an ecosystem, members of the lizards are observed eating members of the insect population.  In this same ecosystem, birds are also observed using insects as a food source.  The relationship between lizards and birds would best be described as –

• predator
•  competitive
• parasitic
• mutualistic

Multiple Choice

Different species are most likely to compete for resources in an ecosystem if both species attempt to –

• occupy the same niche.
• successfully reproduce.
• live in different habitats.         
• find different food sources.   

Multiple Choice

Animals of the same species would most likely compete over a limited amount of -

• minerals
• Oxygen
• sunlight
• mating partners
