Select the wrong statement.

Explanation

The wrong statement is: "Diatoms are chief producers in the oceans."Explanation of the options:1. "The walls of diatoms are easily destructible." - This statement is generally true. Diatom cell walls, also known as frustules, are made of silica and are relatively fragile, making them easily destructible under certain conditions.2. "'Diatomaceous earth' is formed by the cell walls of diatoms." - This statement is accurate. Diatomaceous earth is a sedimentary rock composed of the fossilized remains of diatoms, specifically their cell walls. It is often used for various industrial and agricultural purposes.3. "Diatoms are chief producers in the oceans." - This statement is incorrect. Diatoms are important primary producers in aquatic ecosystems, including oceans, but they are not the chief producers. Phytoplankton, including diatoms, play a significant role in marine food chains, but other microorganisms and algae also contribute to primary production in the oceans.4. "Diatoms are microscopic and float passively in water." - This statement is true. Diatoms are indeed microscopic, single-celled algae that float passively in water. They are a type of phytoplankton and play a crucial role in ocean ecosystems as a food source for various marine organisms.
