Answer:
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.

Explanation:
The food chain starts with primary producers like plants, consumed by primary consumers (herbivores). They in turn are eaten by secondary consumers (usually carnivores), and so on up the chain to the apex consumers. Decomposers break down dead material at all levels, returning nutrients to the ecosystem.
Organisms residing at various levels of the trophic structure in an ecosystem have different food sources. At the base of the food chain, we have primary producers, typically photosynthetic organisms like plants and phytoplankton. These organisms make their own food using sunlight.
The primary consumers are ordinarily herbivores that directly consume the primary producers. Following them are the secondary consumers, usually carnivores that eat the primary consumers. Similarly, tertiary consumers are carnivores that consume other carnivores.
Further up the food chain we have the higher-level consumers who feed on the lower trophic levels. At the top of the food chain are the apex consumers. Meanwhile, decomposers break down dead producers and consumers, returning nutrients to the soil.
