Answer:
They are used as an indicator organism for pathogenic bacteria.
Explanation:
Coliforms are bacteria found in digestive tract of animals and humans. They are non-pathogenic, easy to culture and are used as an alternative indirect testing for presence of other microorganisms. Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.
Therefore the existence of coliforms in water easily indicates feacal contamination.
Food webs are more complex than food chain
Answer:
Their large surface area aids in nutrient absorption.
Explanation:
<u>The main parts of a fungi's body include long, branched hair-like projections called the filaments and an outer cell wall; chitin. The hair-like projections are also referred as hyphae. A complex group of filaments or hyphae is termed as mycelium .As the filaments increase the surface area of fungi, their basic function is to absorb nutrients from external sources. Enzymes for nutrient absorption are released by the filaments on the substrate and hence the nutrients are absorbed. </u>
