Reproduction ensures the continuation of a species by producing new individuals. This process helps pass on genetic information to offspring, allowing species to adapt and survive across generations despite environmental changes.

Living creatures use feedback mechanisms, such as temperature regulation and hormonal adjustments, to maintain homeostasis. These mechanisms help regulate internal conditions and respond to external changes to keep the internal environment stable.
Living creatures grow by increasing in size and complexity. This growth involves cellular multiplication and expansion, development of tissues and organs and overall maturation, driven by genetic instructions and environmental factors.
For a creature to respond to stimuli means it can detect changes in its environment and react accordingly. This response can involve movement, behavioral changes or physiological adjustments to maintain homeostasis.
Seeds with excess water may not germinate due to waterlogging, which reduces oxygen availability, leading to poor respiration and possibly rotting. Class 6 Science NCERT Chapter 10 Chapter 10 Living Creatures: Exploring their Characteristics
Living creatures reproduce through various methods, including sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female gametes, while asexual reproduction involves producing offspring without gamete fusion, like budding or binary fission.
Besides protection, a snail’s shell helps prevent dehydration by reducing water loss. It also provides structural support and serves as a retreat for the snail to hide from threats or harsh conditions.
A snail’s shell grows through the secretion of calcium carbonate by the mantle. As the snail increases in size, the mantle continuously adds new layers to the shell, making it larger.
Non-living things cannot show genuine responses to stimuli. Any apparent response is due to mechanical or chemical processes rather than biological reactions, as non-living entities lack the complexity of living systems.
A snail’s shell helps maintain homeostasis by preventing excessive water loss and protecting the snail from environmental changes. It aids in regulating the internal moisture levels essential for the snail’s survival.
