Answer:
because of inefficiency
Explanation:
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
Answer:
Minerals can form in all geological environments, which allows them to have a wide range of chemical and physical conditions. Two forms of this are temperature and pressure. There are 4 main categories of mineral formations. Igneous is where the minerals crystalize from a melt. Sedimentary is where the raw materials of the mineral are particles from other rocks that have suffered from erosion and weathering. Metamorphic is where new minerals are created from earlier ones owing to the effects of change. Most of the time it's from increasing temperature and/or pressure. Hydrothermal is where the minerals are chemically precipitated from hot solutions in the earth.
Environmental scientists are using GPS ( It is effective but expensive) aerial monitoring (Quick but not the easiest), RFID tags, (mostly for long-term monitoring) and hidden cameras are used to study polar bear behavior without interruption to their environment.
