Question

stability and change deciduous trees lose all their leaves each autumn. how might a pyramid of numbers for a deciduous forest ecosystem change across different seasons? thousands of insects that feed on it, and that feed on the primary consumers. a group of trees may support enough secondary consumers to support a few birds at the upper trophic levels

Explanation:

In a deciduous forest, seasons affect food - availability. In autumn, trees lose leaves, reducing food for primary consumers like insects. This can decrease the number of secondary consumers such as birds that feed on them. In other seasons with more foliage, food is abundant, supporting more consumers at different trophic levels. Ecosystem change across seasons impacts the pyramid of numbers.

Answer:

In autumn, the number of primary and secondary consumers may decrease due to reduced food availability from leaf - loss in deciduous trees. In seasons with more foliage, consumer numbers may increase as food is more abundant.
