The butterfly finds flowering plants for nectar in the meadow. In the process of sucking nectar, they pollinate the plants. The meadow plants such as grasses, forbs and sedges plants provide food for field mice that eat their leaves , roots, and bulbs. The mice also create burrows in the meadow where they breed their young. This, therefore, provides a good hunting ground for owls that prey on mice.

The best answer is A.
The lytic cycle is considered the main cycle in viral replication. Once the viral DNA enters the cell, it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes.
The host cell's DNA is destroyed and the virus takes over the cell's metabolic activity and begins to use the cell's energy for its own propagation and within a short while, when the cell gets overcrowded with the viral progeny, the original virus releases enzymes to break the cell wall. The cell wall bursts. This process is called lysis. The new viruses are then released.
