Really need ! the external coverings of diatoms are made up of [blank1], while slime molds have cell walls containing [blank2]. diatoms are [blank3] because they make food through photosynthesis, while slime molds are [blank4] because they eat decaying plant matter. 1st blank: peptidoglycan, silica, chitin 2nd blank: peptidoglycan, silica, chitin 3rd blank: photoautotrophs, chemoheterothrophs, chemautotrophs 4th blank: heterotrophs, autotrophs, phototrophs

The correct terms for the blanks are - blank1: silica, blank2: chitin, blank3: photoautotrophs, blank4: heterotrophs.

Explanation:

Diatoms are photoautotrophic algae, they have a skeleton made up of silica. Diatoms are found in nearly every aquatic environment. They are photosynthesizing algae that make their own food.

Slime molds are heterotropic in nature like protozoa and were formerly classified as fungi but are now placed in protists.

Thus, the correct terms are - blank1: silica, blank2: chitin, blank3: photoautotrophs, blank4: heterotrophs.

bacterium is not correct

they kick it to the curb.
