Question

1. choose all that apply. what five things do ecosystems need to survive? - tunes - mineral nutrients - people - water - living organisms - silicone dioxide - energy - oxygen 4) choose the best answer. an individual living thing is a(n) ____ - population - community - species - organism

Explanation:

For the first question, ecosystems need mineral nutrients for plant - growth and various biochemical processes, water as a medium for many reactions and for hydration of organisms. Energy (usually from the sun) is essential for photosynthesis and powering the ecosystem, oxygen for aerobic respiration of most organisms, and living organisms themselves to form food - webs and carry out ecological functions. Tunes and people are not fundamental requirements for an ecosystem's survival in a general sense, and silicone dioxide is not among the key survival needs. For the second question, by definition, an individual living thing is an organism. A population is a group of the same species, a community is a group of different populations, and a species is a group of organisms that can interbreed.

Answer:

1. Mineral nutrients, water, energy, oxygen, living organisms
2. Organism
