The statement, that is, the fossil record does not contain any fossil remains of plants, only animals is false.
Explanation:
Any trace of past life is termed as the fossil. It can be an organism's remains like shells, plants, bones, or teeth. Any activity of an organism like burrows, footprints, and feces can be known as a fossil record. Five different ways by which the formation of a fossil takes place are natural casts, permineralization, trace fossils, amber preserved, and preserved remains.
The formation of a fossil distinctly takes place, however, the majority of them formed when an animal or plant dies in a watery environment and gets buried underneath the silt and mud. In the process, the soft tissues quickly get decompose and leave behind the shells or hard bones. With time accumulation of sediments takes place over the top and solidifies into a rock.

The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.

is revealed by the degree of similarity in sections of their DNA
Explanation:
phylogenetic analysis of DNA sequences of two different species are compared and the level of similarity between nucleotide sequences in DNA help to identify their relatedness.
