Aphids are small garden insects. These parasitic pests can appear in great numbers on plants overnight. The female aphid has two different reproductive strategies. When food is plentiful in the spring and summer, she can produce several identical female young per day all by herself. However, in the fall, as food gets scarce, she produces a batch of mixed male and female offspring. These aphids mate and produce more offspring.

Aphids reproduce asexually (A) in spring and summer, but switch to sexual reproduction (S) in fall.

Type A:

Produces several identical female young per day.

Occurs when food is plentiful in spring and summer.

No male parent involved.

Type S:

Produces a batch of mixed male and female offspring.

Occurs when food gets scarce in the fall.

Requires mating between male and female.

Matching:

Type A: Asexual reproduction (A)

Type S: Sexual reproduction (S)

Aphids have two distinct reproductive modes depending on environmental conditions. In favorable conditions, females reproduce asexually (Type A), producing numerous identical female offspring without mating. This rapid reproduction allows aphid populations to explode quickly during warmer months. However, when resources become scarce, females switch to sexual reproduction (Type S), producing diverse male and female offspring that mate and lay eggs, ensuring survival through winter.

Question:-

Aphids are small garden insects. These parasitic pests can seem to appear in great numbers on plants overnight. The female aphid has two different reproductive strategies. When food is plentiful in the spring and summer, she can produce several identical female young per day all by herself. However, in the fall, as food gets scarce, she produces a batch of mixed male and female offspring. These aphids mate and produce more offspring. Match the descriptions of aphid reproduction with the types of reproduction they are describing. Write S for sexual reproducton, and A for asexual reproduction.
