Question

three sand dunes and a cup of water
three cacti, five scorpions and two rattlesnakes
six cacti (plural of cactus) and a cup of sand
three cacti, two rattlesnakes and a cup of sand

Explanation:

In biology, a community refers to all the different populations of living - organisms that interact in a particular area. The option with three cacti, five scorpions and two rattlesnakes represents multiple populations of living organisms. The other options include non - living components like sand and water which are part of the abiotic environment, not part of the community concept.

Answer:

Three cacti, five scorpions and two rattlesnakes
