5. A

Explanation:

A nursery bed can be defined as a specially prepared temporary plot of land or garden which serves as a home for raising seedlings (young plants) prior to planting them in the main location (area). Thus, when older trees in the environment or surrounding dies or are cut-off, these younger plants (trees) propagated in the nursery bed are transferred to replace them.

<em>Some of the criteria or requirements for setting up a nursery bed are;</em>

1. Shed: this is one structure essential in propagating young trees.

2. Location/Site: a place near a source of water should be chosen because water is essential for plant growth and coolness from extreme heat caused by the sun.

3. Storage place for tools and equipment: it is important to have a complete set of tools or their substitute to be able to carry out all nursery activities properly.

4. Boxes, pots, and plots for germinating seeds: there are three places to germinate seeds, young plants, and young trees. Pots are used for germinating young trees while boxes and plots are used for raising seedlings.

An island has many kinds of birds, no native species of snakes, and few large predators. Brown snakes eat bird eggs. What is the
olganol [36]

Boiga irregularis or brown snake is a slender, climbing snake with a vertical pupil and large eyes, providing it better nocturnal vision. The species has no natural predator. When the brown snake is accidentally released into the island, it will result in local extinction of the majority of the island's native lizard and bird species.

It will also result in cascading ecological influences by eradicating native pollinators, resulting in the corresponding reduction of the native plant species.

Hence, the correct answer will be fewer birds and more snakes.
