Which one of the following types organisms occupy more than one trophic level in a pond ecosystem ?
1 Frog
2 Phytoplankton
3 Fish
4 Zooplankton
Explanation:
In a pond ecosystem fishes occupy more than one trophic levels. A fish consuming phytoplankton's occupies primary consumer level while when consuming another small fish, it occupies secondary consumer level. So, a fish can occupy more than one trophic level in a pond ecosystem.

When man eats fish which feeds on zooplankton which have eaten small plants, the producer in the chain is
1 Zooplankton
2 Small plants
3 Fish
4 Man
Explanation:
Trophic level of phytoplankton's. Phytoplankton's are microscopic plants (algae) which occupy the first trophic level in a food chain as they are the producers. Producers are photosynthetic organisms that can synthesize organic molecules using sunlight as an energy source. | (Primary | (Primary | (Secondary (Tertiary | | :---: | :---: | :---: | | producer ) | consumer) | Consumer) Consumer) |

Which one of the following experiments suggests that simplest living organisms could not have originated spontaneously from nonliving matter -
1 Larva count appear in decaying organic matter
2 Meat was not spoiled, when heated and kept sealed in a vessel
3 microbes did not appear in stored meat
4 Microbes appeared form unsterilized organic matter
Explanation:
The simplest living organisms could not have originated spontaneously from non-living matter. - Microbes were killed by heating the meat and sealed vessel where new microbes could not come in the contact with nutrient medium and hence no spoilage of meal takes place. - Pasteur performed experiments in which he took sterilized (by boiling) yeast and sugar solution in a long necked then he bent the neck of swan. After one month he absented that no life appeared in flask solution because the curved flask neck acts as filter. - He later on broken down the neck he found microorganism were originated in solution.

Fungi in a forest ecosystem is
1 producer
2 decomposer
3 top consumer
4 autotroph
Explanation:
Fungi in a forest ecosystem are decomposers. They feed on decaying organic matter and return nutrients to the soil for plants to use. Fungi are the only decomposers that can break down wood and the cellulose in plant cell walls, so they are the primary decomposers in forests.

Energy enters in a food chain through
1 producers
2 primary consumers
3 secondary consumers
4 tertiary consumers
Explanation:
Energy enters in a food chain through producers. Producers are the photosynthetic organisms which harnesses energy from sun and atmosphere to convert it into organic energy which is then consumed by the primary, secondary and tertiary organism.
