Explain how conservation efforts have positively impacted ecosystems.
Conservation efforts have played a crucial role in mitigating the loss of biodiversity, protecting ecosystems, and promoting sustainable development.
Conservation efforts have had several positive impacts on ecosystems. Firstly, the establishment of protected areas and conservation reserves has helped preserve and restore natural habitats, providing a safe haven for wildlife and plant species. This has led to the recovery of many endangered and threatened species, contributing to the overall biodiversity and ecological balance.
Conservation efforts also promote sustainable resource management practices. By implementing regulations and guidelines for fishing, hunting, logging, and other human activities, ecosystems are protected from overexploitation. This helps maintain healthy populations of species, prevents habitat degradation, and ensures the long-term availability of resources.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the correct option is option A.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Water as deep as 60 m is still affected by the wind at the earth’s surface.
Therefore, the correct option is option A.
