Question

why do tropical rainforest plants compete intensely for light? * 1 point
seasonal light variations
dense forest canopy limits sunlight
plants require more photosynthesis
trees grow extremely tall
how do savanna animals like zebras survive seasonal changes? * 1 point
by developing thick fur
through underground burrows
by migrating with rainfall patterns
by storing massive fat reserves

Explanation:

1. In tropical rainforests, the dense forest canopy formed by tall trees blocks much of the sunlight from reaching lower - level plants, so they compete for light. Seasonal light variations are not the main reason for intense light competition. While plants need photosynthesis, the limiting factor here is sunlight availability due to the canopy. The height of trees is a result of competition and not the cause of light competition.
2. Savanna animals like zebras migrate with rainfall patterns. They need water and fresh grass which are available in areas with rainfall. Developing thick fur is for colder climates, underground burrows are more typical for some small animals in deserts or other habitats, and storing massive fat reserves is more common in animals like camels or hibernating animals.

Answer:

1. B. Dense forest canopy limits sunlight
2. C. By migrating with rainfall patterns
