Environmental changes can have significant effects on organisms and ecosystems, as they disrupt the delicate balance of ecological relationships. Organisms have evolved to adapt to specific environmental conditions, and when their environment changes, they may face challenges in survival, reproduction, and overall fitness.

Here are some ways in which environmental changes affect organisms and ecosystems:

Overall, when an organism's environment changes, it can lead to shifts in the abundance and distribution of species, alterations in species interactions, and changes in ecosystem dynamics. Some species may adapt successfully to the new conditions, while others may face challenges or decline in population size.

The cumulative effects of environmental changes on organisms can have broader impacts on ecosystem structure and function, affecting the health and stability of the entire ecosystem. Conservation efforts and the protection of biodiversity are crucial to helping organisms cope with and adapt to environmental changes and to maintain the resilience of ecosystems.

Climate change also alters the life cycles of plants and animals. For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too. Organisms generally slow down or freeze when conditions are cold, but overheat and lose function as temperatures rise. Many species have therefore evolved traits that help protect themselves against extreme temperatures and influence their ecology. When some animals and plants encounter the impacts of climate change in their environment, they respond by changing behavior and moving to a cooler area, modifying their physical bodies to better deal with the heat, or altering the timing of certain activities to match changes in the seasons. Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. Animals can react to climate change in only three ways: They can move, adapt or die. Many animals are moving to higher elevations and latitudes to escape warming temperatures, but climate change may be happening too quickly for most species to outrun it. Erupting volcanoes cause sudden, drastic change in an area, forcing organisms to evolve rapidly to adapt to the new environment. Change in an organism's environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species. Many living things change their environments by building homes, digging in the ground and moving things around. An adaptation can also be behavioral, affecting the way an organism responds to its environment. An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves. Changes in environmental conditions can affect the survival of individual organisms or an entire species. Short-term environmental changes, like droughts, floods, and fires do not give populations time to adapt to the change and force them to move or become extinct. All living things depend on their environment to supply them with what they need, including food, water, and shelter. Symbiosis is a close relationship between organisms of different species in which at least one of the organisms benefits. A variety of local environmental conditions affect the growth of organisms. Genetic factors affect the growth of organisms. The factors that influence the growth of organisms may have more than one cause.
