Because there's not a lot of sun to make them green
There is a chemical in leaves that makes them green during the summer, when the plant is thriving, but in winter or fall, the plant hibernates, which causes a chemical reaction, turning the leaves of the plant red or orange or yellow.
Deciduous trees shed their leaves in the fall in response to changes in temperature and daylight. This process, known as leaf abscission, helps the tree conserve water and energy during the cold winter months.
No, a bryophyllum plant does not grow from spores. Bryophyllum plants reproduce asexually through the production of plantlets along the margins of their leaves, which can then grow into new plants when they fall to the ground.
Listen, they stay alive forever. Falling leaves hit the ground and are gradually biodegraded by bacteria etc, and eventually form leaf mould, which helps enrich the soil. (That's if they are not swept up by the park keeper!)
Aspen leaves are more commonly found in the fall compared to birch leaves.
Deciduous trees lose their leaves in the fall season. This process is called leaf abscission, and it occurs when the tree sheds its leaves in response to changing daylight patterns and cooler temperatures.

Dead leaves that fall to the ground undergo the process of decomposition. They are broken down by decomposers such as fungi, bacteria, and other organisms, which recycle the nutrients back into the soil. This helps enrich the soil and provides nutrients for new plant growth.
It is a chemical change. The substance of the leaves is changing.
In the autumn or fall, leaves begin to lose their chlorophyll and turn different colors. After that, the leaves lose their cohesion and fall to the ground.
Since the leaves turn red in the fall it is not evergreen... the leaves are dying and that's why they turn red... Soon after the leaves turn red they will fall to the ground.

they stay on the ground
