The movement in response to changes in the environment is a protective mechanism for living organisms. For instance, when exposed to bright light or touching a hot object, organisms detect the change and respond with movement to safeguard themselves from ...

The examples include a cat running, which could be in response to seeing a mouse, plants growing towards sunlight, children seeking pleasure and fun while swinging, and buffaloes chewing cud to enhance the digestion of tough food. These movements are ...

We associate visible movements with life because they are seen as responses to changes in the organism’s environment. Movements are considered reactions to environmental changes or attempts by living organisms to use these changes to their advantage.

No, not all movements in living organisms are associated with growth. The paragraph gives examples of movements in animals (like a cat running) and some plants that are not connected with growth but are part of the maintenance functions of ...

In plants, movements can be a result of growth. For example, when a seed germinates and grows, the observable movements, such as the seedling pushing soil aside, are connected to its growth. If growth is halted, these movements would not ...

The initial notion is that if we observe something moving, it is considered alive.

Apart from population size, the paragraph suggests that addressing inequality in society is crucial for improving living standards. If inequality is the main reason for poor living conditions, the size of the population becomes relatively unimportant in the context of ...

No, population size alone is not the only determinant of living standards. Inequality within society plays a crucial role. Even in a smaller population, if there is significant inequality, many people may still experience poor living standards.

The primary concern with an expanding human population is that it makes it more challenging to improve everyone’s standard of living.
