What type of evidence would you look for in a natural setting to indicate that there is competition taking placle among the plan
alexdok [17]

In a study, competition among plants are normal. Hence, all plants required a few basic elements like the light, water, nitrogen, or phosphorus, depending upon the species and the location. Evidence that can conclude that competition do really happen in plants is that some plants release toxins into the soil, in their dropped leaves which wipe out the competition for soil nutrients (such as weeds). And when it come an area with many trees in close proximity such as a forest, height is also indicative of competition for light.

Why are there fewer organisms in each level as you go up the energy pyramid ​
SVETLANKA909090 [29]

Explanation: The energy pyramid describes how energy gets distributed through an ecosystem. The more there is of an organism on the energy pyramid, the more it gives overall to the ecosystem. The less there is of an organism, the less it gives to the ecosystem. Take the Floridian Everglades as an example. There is an abundance of sawgrass, and that makes up the foundation of the system, along with mangroves and such. But there are less of predators in the ecosystem because they only feed of of their prey like small mammals or fish. They never start the food chain, they end it.

lesya692 [45]

Answer:

1s2 2s2 2p4

Explicación:

1s2 2s2 2p4 es la configuración electrónica de la molécula de agua. En el agua, hay 10 electrones, dos de hidrógeno y ocho de oxígeno. La subcapa 2s contiene un máximo de 2 electrones, mientras que la capa 2p puede acomodar seis electrones. El átomo de hidrógeno pertenece al primer grupo y el átomo de oxígeno pertenece al sexto grupo de la tabla periódica. En la estructura de Lewis, un átomo de oxígeno está unido a dos átomos de hidrógeno en un ángulo de 104,45 grados. Existe un enlace covalente presente entre el hidrógeno y el átomo de oxígeno en el que ambos se vuelven estables. El oxígeno necesita dos electrones, por lo que forma enlaces con dos átomos de hidrógeno que tienen un electrón cada uno.
