What happens to energy as it moves from a producer to the top consumer?
More energy is gained with each organism that is eaten.
The energy remains constant.
It depends on which producers and consumers are involved that determines whether energy is gained or lost.
Most of the energy is lost.
An organism that makes complex, energy-containing biomolecules from simple inorganic molecules using energy captured from light or inorganic chemical compounds

What do the arrows in food chains and food webs represent?
The arrows point to what will be eaten.
The arrows point in random directions.
The arrows point in the direction the life cycle moves.
The arrows point in the direction the energy flows.
"One way matter is cycled through both the living and nonliving parts of an ecosystem is - "
A snake consumes a mouse.
Oxygen is released into the atmosphere.
Decomposers break down carbon from once living things and return it to the nutrients of the soil for plants to use.
Scavengers break down carbon from once living things and return it to the nutrients of the soil for plants to use.
A food web diagram is provided.
(See attached diagram)
Which of the following organisms depend only on producers for energy?
Diatoms
Shrimp
Amphipods
Squid
Matter is passed from the living part of an ecosystem to the non-living part when which of the following takes place?
Plants absorb gases
Plants decompose
Animals eat plants
Animals drink water
The energy organisms need to live and grow first enters the ecosystem when –
plants take in light energy from the Sun.
decomposers break down dead organisms.
primary consumers eat plants for food.
secondary consumers eat primary consumers.
A food web diagram is provided.
(See attached diagram)
Based on the diagram, it is reasonable to conclude that matter could follow which of the following paths as it cycles through this ecosystem?
Sun --> grass --> robin
Plant seeds --> field mouse --> robin
Eagle --> deer --> plant seed
Grass --> deer --> mountain Lion
Which of the following observations would support the claim that as plants absorb sunlight to make food, they release oxygen into the environment?
Oxygen concentration in the atmosphere was much higher millions of years ago when different plants existed.
When plants are kept in a sealed environment, the concentration of carbon dioxide steadily goes down.
Plants that are kept under conditions of total darkness fail to grow normally and eventually will die.
The oxygen concentration in a pond with many plants increases during the day and decreases at night and on cloudy days.
