1 matching 2 points
match the biome with its correct description
savannah
grassland
desert
dominated by grasses and have few trees, known for their rich soils and vast open landscapes.
tropical grasslands with scattered trees, experiencing a wet and dry season
very low precipitation, resulting in sparse vegetation
2 multiple choice 2 points
what impact does climate change have on the distribution of species and biodiversity?
it promotes the migration of species to new habitats.
it leads to more stable ecosystems.
it increases genetic diversity within species
it causes a shift in species distribution and loss of biodiversity.

Explanation:

1. For the matching question about biomes: A savannah is tropical grasslands with scattered trees, experiencing a wet and dry season. Grasslands are dominated by grasses and have few trees, known for their rich soils and vast open landscapes. Deserts have very low precipitation, resulting in sparse vegetation.
2. For the multiple - choice question about climate change: Climate change disrupts habitats, causing species to migrate to more suitable areas and often leading to a loss of biodiversity as some species may not be able to adapt or migrate in time. It does not lead to more stable ecosystems or increase genetic diversity within species in a positive way in the context of its overall impact.

Answer:

1. Savannah: tropical grasslands with scattered trees, experiencing a wet and dry season

Grassland: dominated by grasses and have few trees, known for their rich soils and vast open landscapes
Desert: very low precipitation, resulting in sparse vegetation

1. It causes a shift in species distribution and loss of biodiversity.
