1An ecosystem is made up of......
- Aa group of living things and their physical surroundings; different communities
- Bindividual organisms; only living things
- Cgroups of the same species; populations
2[blank_start]Photosynthesis[blank_end] happens when a plant uses the Sun's energy to convert water and carbon dioxide into carbohydrates such as sugars and starches.
- APhotosynthesis
- BSunlight
- CProducers
3What do decomposers do? (click all that apply)
- AConsume waste and dead organisms to get energy
- BReturn nutrients to the soil, water, or air.
- CBreak down material from waste and dead organisms.
4No energy is lost in an ecosystem.
- ARichtig
- BFalsch
5Nutrients are continuously lost through the food web.
- ARichtig
- BFalsch
6Which of the following are nutrients in an ecosystem? (check all that apply)
- Awater, carbon, oxygen
- Bnitrogen, calcium,
- Cproducers, consumers
7Producers take in [blank_start]carbon dioxide[blank_end] during the process of photosynthesis and release [blank_start]oxygen[blank_end].
- Acarbon dioxide
- Boxygen
- Coxygen
- Dcarbon dioxide
8[blank_start]Consumers[blank_end] take in oxygen for their life processes and release carbon dioxide.
- AConsumers
- BProducers
9A [blank_start]producer[blank_end] is a type of organism that undergoes photosynthesis, converting energy into a usable form of food for other organisms in an ecosystem.
- Aproducer
- Bconsumer
10What form of energy is lost by moving from producer to consumer to decomposer in an ecosystem?
- Alight
- Bheat
- Cfood energy
11A [blank_start]producer[blank_end] is a living thing that can make its own food.
- Aproducer
- Bconsumer
12A [blank_start]consumer[blank_end] is a living thing that eats other living things for food and energy.
- Aconsumer
- Bproducer
13How is a food web different from a food chain?
- AFood webs are a group of overlapping food chains in an ecosystem.
- BFood webs include at least one spider as a primary food source.
- CFood chains are more complex than food webs.
14In a food web or food chain, carnivores are the most plentiful (numerous) member of the ecosystem.
- ARichtig
- BFalsch
15What is an energy diagram?
- AA diagram that shows how energy moves from one feeding level to the next in the food chain.
- BAlternate forms of energy available to animals in an ecosystem.
- CA diagram which shows how each member of an ecosystem gets its food.
16Which of the following is true about an energy pyramid? (check all that apply)
- AThere are more producers than herbivores or carnivores in the ecosystem.
- BAs you move up to the top of the pyramid from producer to consumer, the diagram becomes smaller and smaller to show how less and less energy is available.
- CEnergy drops about 10% from each level of the pyramid.
17[blank_start]Symbiosis[blank_end] is an interaction where two species live together for a long time and at least one of the species benefits.
- ASymbiosis
- BCompetition
- CPredator-Prey
18[blank_start]Competition[blank_end] happens when two or more species depend on the same food source or any limited resource.
- ACompetition
- BSymbiosis
- CPredator-prey relationship
19In symbiosis, both organisms must benefit from an interaction.
- ARichtig
- BFalsch
20Predator-Prey relationships are bad because a cute animal gets killed.
- ARichtig
- BFalsch
21A [blank_start]population[blank_end] is a group of individuals of the same species living in a given area.
- Apopulation
- Bbiosphere
- Cecosystem
- Dcommunity
22The change in size of population over time is called its [blank_start]growth rate[blank_end].
- Agrowth rate
- Bcommunity
23What limits population growth? (check all that apply)
- AThe amount of food available.
- BThe amount of space available.
- CCompetition from different species for food.
24What is a pollutant?
- AA variable that causes harm to an organism.
- BAn invasive species.
- CCompetition between two species for the same prey.
25What often determines how harmful a pollutant is? (check all that apply)
- AThe pollutant's ability to cause harm.
- BThe amount of pollutant in the air, water, or soil.
- CHow long the pollutant stays in the air, water, or soil.
26Why are toxins heavily concentrated at higher predator levels in the food chain?
- ABecause toxins are stored in the fatty tissues of animals and are not passed out of their body. This multiplies as one moves higher up the food chain.
- BBecause higher level predators like the taste of toxins.
- CBecause only top carnivores store toxins in their body.
27What are some examples of pollutants?
- Amercury and sulfur dioxide
- BThe European Green Grab and the Cane Toad
- CTurbidity and pH scale
