1. Scarcity of resources can impact the survival of organisms and the longevity of a population by limiting their ability to obtain essential resources such as food, water, shelter, and space. Organisms may compete for these resources, leading to increased stress, decreased reproductive success, and ultimately a decline in population size. Additionally, scarcity of resources can cause individuals to disperse in search of resources, which can further impact population dynamics and genetic diversity.
2. The biological components of an ecosystem, such as predators, prey, producers, and decomposers, play a crucial role in regulating population dynamics. For example, predators can control the population size of prey species, preventing them from overpopulating and depleting resources. Producers provide energy for the ecosystem, while decomposers break down organic matter and recycle nutrients. Changes in the abundance or distribution of these biological components can have cascading effects on populations and ecosystem health.
3. Human activity can change ecosystems and populations in various ways, such as habitat destruction, pollution, overexploitation of resources, and introduction of invasive species. These activities can disrupt the balance of ecological systems, leading to declines in biodiversity, reduced ecosystem services, and increased vulnerability to environmental stressors. For example, deforestation can destroy habitats and displace wildlife, while pollution can contaminate water sources and harm aquatic populations. By understanding and mitigating the impacts of human activity on ecosystems, we can work towards promoting the sustainability of populations and ecosystems.

1. Not having enough resources can make it hard for animals to survive and can make a population die out. If there's not enough food, water, or shelter, animals might not be able to find what they need to live. This can make them fight for resources, stress out, not have babies, and eventually have fewer animals in the group.
2. In nature, different plants and animals help each other in an ecosystem. For example, predators eat prey to keep their numbers in check, while plants provide energy for all living things. When there are changes in the ecosystem, like if the predator population grows too big, it can affect everything else in the ecosystem.
3. People can have a big impact on nature. By chopping down forests, polluting water, taking too many resources, or bringing in new plants or animals, humans can mess up ecosystems. This can lead to less variety in plants and animals, less clean water, and more problems for the environment. We need to be careful not to harm nature too much.
