What does a food web represent?

• All connections of energy flow throughout all organisms in a habitat.
• The specific ways that mutualism is carried out.
• A single pathway or energy flow between organisms. 
• How carnivores get their food. 

Organisms that feed on dead organisms or waste and recycle nutrients are called

• herbivores

• decomposers

• autotrophs

• carnivores

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

The diagram below represents a developing fetus in a human. What would most likely happen if structure X were damaged in the early stages of pregnancy?

• The genes from the mother would not be turned on in the fetus.

• The nutrients necessary for development would not be able to reach the fetus.

• The fertilized egg would not be able to travel from the ovary to the uterus.

• Development would take longer since the fetus would have to synthesize nutrients.

Which statement best describes an important process carried out by structure X in the diagram?

• Milk passes from the mother to the fetus.

• Materials are exchanged between fetal and maternal blood.

• Maternal blood is converted into fetal blood.

• Oxygen diffuses from fetal blood to maternal blood.

For a human zygote to become an embryo, it must undergo

• fertilization

• recombination

• meiotic divisions

• mitotic divisions

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• Active Transport

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

The diagram illustrates the movement of glucose across a cell membrane. Which two processes are most directly represented in this diagram?

• ATP synthesis and the diffusion of water

• molecule transport and energy use

• homeostasis and ATP synthesis

• homeostasis and the diffusion of water
