Biotic and Abiotic Factors

​Each of these has a significant role in the survival of the ecosystem.

Biotic factors can’t survive without abiotic factors.
Consumers can’t survive without producers.

The ecosystem can’t regenerate without the help of decomposers

Cada uno de estos tiene un papel importante en la supervivencia del ecosistema.

Los factores bióticos no pueden sobrevivir sin factores abióticos.

Los consumidores no pueden sobrevivir sin los productores.

El ecosistema no puede regenerarse sin la ayuda de los descomponedores

Energy Flow

- Arrow points in the direction the energy is flowing/La flecha apunta en la dirección en la que fluye la energía

- Ultimate energy on Earth comes from the sun/La última energía en la Tierra proviene del sol

- Producers (autotrophs) convert the sun’s energy to glucose (photosynthesis)/Los productores (autótrofos) convierten la energía del sol en glucosa (fotosíntesis)
- Consumers (heterotrophs) get their energy from producer/Los consumidores (heterótrofos) obtienen su energía del productor

- Only about 10% of the energy is available to the next trophic level/Solo alrededor del 10% de la energía está disponible para el siguiente nivel trófico

- The rest “escapes” as heat/El resto “se escapa” en forma de calor

What is Water Cycle?/Que es el Ciclo de Agua?

Water cycle is one of nature's cycles. It is the continuous movement of water from the Earth's surface to the air and back to the Earth's surface.

​El ciclo del agua es uno de los ciclos de la naturaleza. Es el movimiento continuo de agua desde la superficie de la Tierra hacia el aire y de regreso a la superficie de la Tierra.

Watersheds

A watershed is all the land that water can flow over and drain into a larger body of water. Humans can impact a watershed in a negative way by using fertilizers, pesticides, pet wastes, and leaking car oil. Urbanization (more concrete, less green space) can affect area flooding

​Una cuenca es toda la tierra sobre la que el agua puede fluir y drenar en un cuerpo de agua más grande. Los humanos pueden impactar una cuenca hidrográfica de manera negativa al usar fertilizantes, pesticidas, desechos de mascotas y fugas de aceite de automóviles.
