An example would be acid rain, cuz it is sometimes natural (not all of it is caused by humans). So, when acid rain falls it kills many marine creatures, and this will eventually lead to a gap in the food chain.
Tropism is the directional growth response of a plant in response to a stimulus. Two examples of tropism are phototropism, where plants grow towards light, and gravitropism, where plants grow in response to gravity.
Examples of stimulus reaction in plants include phototropism (response to light), gravitropism (response to gravity), thigmotropism (response to touch), and hydrotropism (response to water). These responses allow plants to adapt to their environment and optimize their growth and survival.
An automatic response to the environment is a reflex

Plants respond to stimuli through growth movements. For example, phototropism is their response to light, causing them to grow towards it. Thigmotropism is their response to touch, triggering growth in response to physical contact. These responses help plants adapt and survive in their environment.
