Answer:
False
Explanation:
Diffusion uses the concentration gradient that has been set up, this is a naturally occurring phenomena, and using a diffusion gradient some small particles can cross over the cell membrane. Some bigger or polar molecules require facilitated diffusion to move these molecules across the membrane.
Facilitated diffusion still uses the gradient for passive transport. This means that ATP is not used to transport molecules.
The reason that glucose will not move into the cell via passive transport is because there is a higher concentration of glucose inside the cell, meaning it needs active transport to move glucose (against the concentration gradient) into the cell.
Answer:
D. Water changes state when it loses or gains energy.
Explanation:
When water gains energy, it turns from ice to water, or water to gas. When water loses energy, it turns from gas to water, or water to ice.
Particles in the water move faster and create more energy when heated, and this causes them to spread wider apart and change. Particles slow down and move closer together when they get cold.
Answer A:
The organism which provides energy directly and/or indirectly to all of the other organisms is the garden plants.
Explanation:
Plants are generally found at the lowest part of the pyramid/food chain. They are also called Autorotrophs because they are the primary producers of energy from which the entire pyramid feeds off.
The other animals/organisms on the pyramid are called Heterotrophs because they depend directly or indirectly on the primary energy producers.
Answer B:
The Slug and the Aphid feed are herbivorous. So they are in competition for the garden plants. If one of them, for some reason, decreased in population, the other will have more food to eat.
