Fermentation and cellular respiration differ in that fermentation does not require oxygen while cellular respiration does.
No, in facilitated diffusion molecules move against their concentration gradient. Facilitated diffusion is diffusion that requires an input on energy; moving against the concentration would require that energy.
The correct answer is the control variable. For example, if you want to measure how men and women like cats, you would present the same cats to all the people (that;s the constant variables) and gender is your control variable.

I hope this helps! I like bio
Secondary consumers receive less energy from the food chain than primary consumers.
Primary consumers are herbivores, meaning they eat the plants that have 100% energy.
Secondary consumers are either omnivores or carnivores. This means that they eat both animals and plants. In the situation that a secondary consumer is a carnivore, the secondary consumer is receiving less energy from the primary consumer.
Hope this helps!
