Question

a sheet-web weaving spider found in the grasslands of the desert
When investigating sheet-web weaving spider at a larger spatial scale, scientists found that spiders prefer large depressions (habitats with flowering shrubs, leaf litter, and animal feces that attract insect prey) in grassland. Thus, these suitable habitats are where you can find many spiders. The congregation of sheet-web weaving spiders among these suitable habitats generates the.............(random, uniform or clustered) dispersion pattern in a grassland at larger spatial scale.
However, high quality sites for web building are limited within these suitable habitats. The presence of other spiders in close proximity reduces the fitness of the resident spider. The resident spider will actively patrol their web-sites and engage in aggressive behavior towards other spiders enter into their territory within the habitat. Such aggressive interactions between spiders generate...................(random, uniform or clustered) dispersion patterns of sheet-web weaving spiders within each suitable habitat.

Answer 1

1. The congregation of sheet-web weaving spiders among these suitable habitats generates the...uniform..........(random, uniform or clustered) dispersion pattern in a grassland at larger spatial scale.

Explanation: Uniform dispersion: sheet-web weaving spider will be spaced more or less evenly in these suitable habitats.

2. The resident spider will actively patrol their web-sites and engage in aggressive behavior towards other spiders enter into their territory within the habitat. Such aggressive interactions between spiders generate.....clustered........(random, uniform or clustered) dispersion patterns of sheet-web weaving spiders within each suitable habitat.

Explanation: Clustered dispersion: As the spiders aggregate in patches and also caused by aggressive behavior between spiders.
