Answer 1

as in 2. fungi are impostant part of the nutrient cycle the ecosystem. Fungi belps to control the pest population they are animal pathogens. They have an impor- tant role in medicine by providing antibiotics, maintain the fontility of soil. helping in agricuurural field, and they form an important form of food. Fungi are decomposers and bring about recycling of matres by decomposing dead animal and plant mattels in the soil, to make it fertileAntibiotics produced by fungi are useful against disease pathogens. Some of these antibiotic are used to feed animals fos speedly 970wth and to improve meat quality.

Ascosponde are produced in ascocarp and basidiospores are produced in the basidiocarp () zoospores are movile asexual spores of fungi andi Other onganisms we Hagellam for locomotion. Ascospores are spores produced inside the ascus. This is specific to fungi classified as ascomycetes. d).
