NEET BIOLOGY

Detailed explanation-1: -Litter (dead plant material of a small size that is loose on the ground) can facilitate or impede plant growth, by altering temperature, moisture, and light availability (Facelli and Pickett 1991, Baskin and Baskin 1998), and can affect life history stages differently (Muturi et al. 2017).

Detailed explanation-2: -Human activity, as seen with species extinction, the introduction of non-native plants, climate change, and pollution, is a large contributor to change in plant communities.

Detailed explanation-3: -Litter can spread diseases, viruses and parasites through two methods, direct and indirect contact. Germs can be transmitted directly by physically coming into contact with litter. This can happen by picking up, touching, or by accidentally injuring themselves on improperly disposed of trash.

Detailed explanation-4: -Another outside factor that affects plant growth is human activity. We can add fertilizers to make plants grow bigger, faster. We can also harm plants through deforestation, pollution, and forest fires, which can tarnish their soil and water.
