Final answer:
The biome type for rainforests, mangroves, and degraded savanna is Tropical. Rainforests have a dense canopy and high biodiversity, mangroves protect shorelines, and savannas are grasslands with seasonal rainfall.
Step-by-step explanation:
The type of biome represented by rainforests, mangroves, and degraded savanna is Tropical (Option A). These biomes are characterized by their warm temperatures throughout the year and typically receive a high amount of rainfall, except for the savanna, which has a more seasonal rainfall pattern.
Rainforests are known for their dense canopies and high biodiversity, mangroves are coastal ecosystems that are crucial for protecting shorelines and supporting a variety of species, and savannas are grasslands with scattered trees with a distinct dry and wet season.
Answering the reference questions: The biome characterized by short growing seasons is the Arctic tundra (Option C). The false statement about biomes is that boreal forests are dominated by deciduous trees (Option C) - in reality, they are dominated by coniferous trees. Low precipitation, cactus, hardy shrubs, and high temperatures are characteristic of deserts.
