European Starlings have a significant impact on their environment because they congregate in such large numbers. They probably play a role in seed dispersal because of their consumption of a wide variety of fruits. European Starlings also control some insect populations, but since they will eat almost anything they cannot be relied upon to eat only pests. Insects they are known to feed on include the larvae of craneflies (Tipulidae) and moths (Lepidoptera) as well as mayflies (Ephemeroptera), dragonflies and damsel flies (Odonata), grasshoppers (Orthoptera), earwigs (Dermaptera), lacewings (Neuroptera), caddis flies (Trichoptera), flies (Diptera), sawflies, ants, bees and wasps (Hymenoptera) and beetles (Coleoptera). They will also eat small vertebrates such as lizards and frogs, as well as snails (Gastropoda) and earthworms (Annelida). European Starlings have a particular technique of inserting their closed bill into the ground or an object and then prying the bill open, creating a small hole. This allows them to forage efficiently in soil and among roots as well as in feed troughs and on the backs of ungulates where they search for ectoparisites.
Answer
The correct sequence is given below.
Explanation:
A. NAD+ (It recieves electrons directly from substrate in glycolytic as well as Citric acid cycle reactions)
B. Oxidoreductase (It is present as complex I termed NAD+-CoQ oxidoreductase. It receives electrons from NADH)
C. Quinone (It is present as Ubiquinone in complex III of Electron transport chain. It receives electrons from NADH and FADH2)
D. Terminal oxidase (It is complex IV of electron transport chain termed as Cyt c oxidase)
E. Oxygen (It is the final acceptor of electrons and gets reduced to water)
Answer:
rhizobia is an important nitrogen fixing bacteria found in the soil to help grwo plants like legumes. rhizobia enter into a symbiotic relationship withe legumes
Explanation:
rhizobia and legumes coexist by entering into a symbiotic association. rhizobia is a bacteria that fixes nitrogen molecules for the legumes and in return the legumes provide the bacteria with food and nutrition.
If rhizobia becomes extinct in the near future it would be difficult for plants like legumes to grow as they wouldn't get sufficient nitrogen and nitrogen is an important nutrition for the plant to grow and develop. Thus it can cause rapid depletion or death of plants that need rhizobia to fix nitrogen molecules for them.
Answer: To show how different members of a species are related.
