The marine invertebrates of phylum Cnidaria are called corals. Corals are important as they build reefs in oceans and feed on planktons.
The given statement is :
<u>True</u>
The position of corals can be explained as:
The corals are both a primary producer as well as the consumer.
They take energy from algae through the mutual relation between both organisms. The corals feed on planktons, zooplanktons and phytoplankton for energy so they are consumers.
The algae living in coral make food for them and corals produce oxygen.
The cell wall of oomycetes, however, is not composed of chitin, as in the fungi, but is made up of a mix of cellulosic compounds and glycan. The nuclei within the filaments are diploid, with two sets of genetic information, not haploid as in the fungi.
Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings.
