The nematophagous fungi are of three main types on the basis of ecological habit: 1. Nematode-Trapping Fungi 2. Endoparasitic Fungi and 3. Egg Parasites. Type # 1. Nematode-Trapping Fungi: Fungi capturing nematodes are called nematode-trapping fungi. Such fungi have evolved structural adaptations to trap or penetrate their prey. They may be predatory or endoparasites. There are varieties of ways by [...]
Here is a list of four major microbial interactions:- 1. Clay-Humus-Microbe Interaction 2. Plant-Microbe Interactions 3. Animal-Microbe Interactions 4. Microbe-Microbe Interactions. 1. Clay-Humus-Microbe Interaction: Clay mineral (and humic substances) affects the activity, ecology and population of microorganisms in soil. Clays modify the physicochemical environment of the microbes which either enhance or attenuate the growth of individual microbial population. After release [...]
Microorganisms which live in soil are algae, bacteria, actinomycetes, bacteriophages, protozoa, nematodes and fungi (Fig. 30.2). A brief description of soil microorganisms has been given below: 1. Soil Algae: Soil algae (both prokaryotes and eukaryotes) luxuriantly grow where adequate amount of moisture and light are present. They play a variety of roles in soil. One of the important role of [...]
