Verdich [7]2 years ago

Answer:

Una comunidad biótica no contiene, por lo general, el mismo número de plantas y animales. Frecuentemente una o más especies tendrá una particularmente fuerte influencia sobre la naturaleza de la comunidad entera. Dichas especies se les refiere como las dominantes. Las especies dominantes de la comunidad son usualmente los productores - o los consumidores - principales de energía en cada nivel. Así, sobre un estrecho pastizal, ciertos tipos de pastos podrían ser las plantas dominantes, los insectos come-plantas, los herbívoros dominantes, y los pájaros come-insectos, los predadores dominantes. Los ecosistemas simples frecuentemente tienen solamente una especie dominante en cada nivel. Así pues, suele resultar más difícil, para una sola especie ser la dominante en ecosistemas complejos.

Aunque una comunidad puede englobar cientos de miles de especies vegetales y animales, muchas son relativamente poco importantes, de modo que únicamente algunas, por su tamaño y actividades, son decisivas en la vida del conjunto.

En las comunidades terrestres las especies dominantes suelen ser vegetales por dar alimento y ofrecer refugio a muchas otras especies; de esto resulta que algunas comunidades se denominan por sus vegetales dominantes, como artemisa, roble, pino y otras.

Comunidades acuáticas que no contienen grandes plantas conspicuas se distinguen generalmente por alguna característica física: comunidad de corrientes rápidas, comunidad de lodo plano y comunidad de playa arenosa.

A state's taxes are determined by
Delvig [45]

Answer:

Basically, taxes are determined according to the expense of the state

Explanation:

he United States of America through the Constitution has granted the Federal Government the authority to impose taxes, and states have the right to impose taxes except for the ones that are forbidden by the Constitution.

Taxes help states to obtain enough income to help their governments. With this income, they're able to provide public services such as school, police protection, health services, and even the government.

Basically, taxes are determined according to the expense of the state. For example, most of the states require their residents to pay a personal income tax but is mandatory to pay for the property tax in all 50 states, according to their own definition of property. States take into account the taxable income of individuals, corporations, and trusts before imposing a tax.
