Question: Answer the following question given this paragraph: In all biomes, ecosystems need a constant input of energy. Matter, on the other hand, is constantly recycled in ecosystems. Q: While matter is recycled, ecosystems need a constant input of what? A:
OPTIONS:
- heating
- food
- light
- energy
Answer: energy

input with options: Answer the following question given this paragraph: Another mechanism besides diffusion to passively transport materials between compartments is filtration. Unlike diffusion of a substance from where it is more concentrated to less concentrated, filtration uses a hydrostatic pressure gradient that pushes the fluidand the solutes within itfrom a higher pressure area to a lower pressure area. Filtration is an extremely important process in the body. For example, the circulatory system uses filtration to move plasma and substances across the. Q: What is used during filtration to push fluids and solutes, from higher pressure areas to lower pressure areas? A:
OPTIONS:
- constructs pressure gradient
- limited pressure gradient
- magnesium pressure gradient
- hydrostatic pressure gradient
output: hydrostatic pressure gradient

Q: Answer the following question given this paragraph: For a long time, scientists classified fungi as members of the Plant Kingdom. Fungi share several obvious traits with plants. For example, both fungi and plants lack the ability to move. Both grow in soil, and both have cell walls. Some fungi even look like plants. Q: What group of organisms was initially misclassified as plants because they also lack the ability to move, grow in soil, and have cell walls? A:

OPTIONS:
- protozoa
- algae
- gymnosperm
- fungi

A:
fungi
