Question

tallgrass prairies are ecosystems with very hot summers and very cold winters. the main stems of most prairie plants run underground where they are protected. a few trees live in the prairies, mostly along creeks. animal species that are found in the prairies include rodents, birds, and grazing mammals such as bison and deer. which three statements best explain the importance of animal grazing and wildfires to organisms in a tallgrass prairie ecosystem? grazing animals spread grass seeds and open new spaces for seeds to germinate, which counteract the affects of wildfires. grazing animals eat trees around the creeks, raising the water level of the creek wildfires burn the underground plant stems, increasing the food available for grazing animals. grazing prevents the grasses from becoming too large and losing their nutritive value for herbivores. wildfires remove dead plants and leaves that cover the ground and block sunlight from reaching new plant shoots

Explanation:

1. 放牧動物は草の種を広げ、種が発芽するための新しいスペースを開きます。また、放牧は草が大きすぎて草食動物にとって栄養価を失うことを防ぎます。野火は地面を覆い、新しい植物の芽に日光が届かなくする枯れた植物や葉を取り除きます。これらはすべて高草草原の生態系にとって重要です。
2. 放牧動物が川沿いの木を食べることで川の水位が上がるという説明は一般的ではありません。また、野火が地下の植物の茎を燃やすことはあまりありません。

Answer:

• Grazing animals spread grass seeds and open new spaces for seeds to germinate, which counteract the affects of wildfires.
• Grazing prevents the grasses from becoming too large and losing their nutritive value for herbivores.
• Wildfires remove dead plants and leaves that cover the ground and block sunlight from reaching new plant shoots.
