Answer:
Producers
Explanation:
Organisms who make (or produce) their own food are called producers, <em>plants are capable of self-feed through the process of photosynthesis, therefore, they are producers.</em> These producers are the first energy source for primary consumers and the star of the living food chain. Consumers are animals that consume other organisms, they are divided into three categories: primary (herbivores), secondary (carnivores and omnivores), tertiary consumers (they consume energy from all other levels). The final link in this food chain is the decomposers, also known as detritivores, they eat decaying or dead matter including dead plants or animals, returning vital nutrients to the soil.
Biomagnifiers are organisms that tolerate increasing concentration of a substance at successively higher levels in a food chain. A bioaccummulator is an organism that suffers a net accumulation of a contaminant from all sources including water, air, and diet. Biomagnifiers and bioaccumulator can be from plants to animals all across the food chain.

Answer:
Los conflictos bélicos tienen varias causas por las cuales se generan, pero una de las más comunes se da por cuestiones limítrofes o de recursos naturales, donde dos o más naciones se enfrentan por no poder delimitar pacíficamente sus diferencias al respecto.
Durante la historia han habido innumerables ejemplos de este tipo de conflicto, como por ejemplo la Guerra de Malvinas entre Argentina y Gran Bretaña, la Guerra del Chaco entre Bolivia y Paraguay, la Guerra del Cenepa entre Ecuador y Perú, o la Guerra Mexicano-Estadounidense por Texas y California en 1845.
En todos estos casos, los conflictos han surgido por diferencias en los límites entre ambos países. En algunos casos, la situación luego de la guerra no cambió, pero en otros como la Guerra Mexicano-Estadounidense los límites cambiaron completamente: en esa guerra México perdió cerca de la mitad de su territorio a manos de los Estados Unidos.
En este ejemplo, podemos ver como el mapa político de América del Norte fue modificado por la guerra: los límites entre ambos países cambiaron, con un país ganándole territorio a su contrario. Así, sucede muchas veces que las guerras terminan modificando los mapas políticos, cambiando fronteras y ajustándolas a nuevas realidades luego de los conflictos.
Answer:
In general, it is the climates (specifically temperature and its range, and the nature and availability of precipitation) that exert major influences on the geomorphic processes operating in particular zones of the land surface.
Explanation:
Answer: C.
Air masses that are hot and dry, and are responsible for heatwaves of summer in the western half of the United States.
Explanation: Air masses have fairly uniform temperature and moisture content in the horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the underlying surface properties where they originate.
Air that stands over the Caribbean Sea, for example, becomes a warm, humid maritime tropical air mass, while air that lies in the Arctic regions of northern Canada takes on the cold and dry characteristics of its surroundings and becomes a continental polar air mass.
<span>In the 20th century, the scientist believed
that the floor of the ocean floor is flat. But later on discovered that their
theory is wrong. The ocean floor is not flat and featureless. One technology
helped the scientist to study in advance and in details the real feature of the
ocean floor. They used sound waves to know the distance of the water from floor
level to the top. They also discovered that ranges of mountains lies under the
ocean. Sonar was one of the technologies they used to study the sound waves
emitted by the ocean.</span>
