Cycling of Matter and Energy Quick Check

1.While detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms.

2.Food webs are more complex than simple food chains.

3.heterotrophs

4.autotroph

5.Matter and energy are cycled through the ecosystem.

Explanation:

:)

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
