Organisms face big challenges when trying to live in different environments around the world. These places include deserts, forests, and tundras. The tough conditions in these areas can cause physical stress, limit resources, and increase risks from predators.

1. Desert Challenges:

• There isn't much water, which can lead to dehydration.
• The high temperatures can make animals and plants feel very hot.

Solutions:

• Some species develop special features to help them survive in dry areas.
• For example, they may have thick skin or change their habits to be active at night when it's cooler.

2. Forest Challenges:

• There is a lot of competition for sunlight and nutrients.
• Many herbivores eat plants, which can harm plant populations.

Solutions:

• Plants might grow tall or have large leaves to reach sunlight.
• Animals can use camouflage or mimic the colors and shapes of their surroundings to avoid being seen.

3. Tundra Challenges:

• The temperatures are extremely low, and the growing season is very short.
• There is not much food available, which makes it hard to survive.

Solutions:

• Some organisms develop features to keep warm, like blubber or thick fur.
• Others may go into hibernation to survive the cold months.

In conclusion, while these adaptations help organisms cope with their environment, climate change makes things even more difficult. This can upset the balance in each biome.
