Продуктивность зрелых экосистем близка нулю. Чем это объясняется?

Ответы

Автор ответа: Jendosina5

Чем больше развита экосистема, то есть чем она ближе к своему зрелом состоянию, тем выше её продуктивность. Так лес, например, в своём зрелом состоянии даёт наибольший "урожай" травянистых, мха, листвы, грибов, ягод по сравнению с молодым лесом, и, следовательно, характеризуется наибольшей продуктивностью.

It is sunny today. It is very hot. We are hot. We take a big towel, three cups, three plates, some milk, some meat, three apples and go to the lake.

The lake is big and the water in the lake is cold. We swim and play. Then we go out. Blackie does not go out. He is in the lake.

"Go out!" says Pinky. "The water is not warm. It is cold."

"I am not cold," says Blackie. "I like the water!"

"Pinky," I say. "Let's eat our breakfast."

"But we can't. Blackie is in the lake." "Yes, we can," I say. I take a piece of meat, eat it and say:

"Look, Blackie! I am eating our meat! It is very nice!"

Blackie looks at me and says:

"Eat the meat. I can fish here."

So Blackie is in the water. The water is cold. Pinky is not happy. She is sad. She looks at me and says:

"Reddy, what can we do?"

"Wait and see," I say.

Blackie is fishing now. He is not looking at me. I walk into the water and dive. Now I am under the water. I swim to Blackie under the water. Now I can see his legs. I open my mouth and bite him.

"Help!" cries Blackie. "There is a monster in the water."

Blackie runs out of the water.

"There is a monster in the lake!" he says to Pinky.

"A monster?!" cries Pinky.

"Yes, it has got red ears and very sharp teeth!"

Pinky looks at Blackie. She knows that monster but she says:

"Don't go into the water again! I know that monster. It is in one of my books. It is a terrible monster!"

"OK," says Blackie. He is afraid. He looks at Pinky and says:

"And where is Reddy?"

"Oh no!" cries Pinky. "He is in the water!"

"Oh no!" cries Blackie. "The monster can bite him!"

They look at the lake. I am swimming in the lake.

"Reddy, come out!" cry Pinky and Blackie. "There is a terrible monster in the water!" says Blackie.

"Is it big?" I ask.

"It is long and it has got red ears and very sharp teeth!"

"But I am not afraid of monsters. I have got sharp teeth, too," I say. "I am not going out. The water is warm now. Don't wait for me. Have breakfast."

"Oh!" says Pinky. "Again."

She looks at Blackie.

"What about a monster with a black tail?" she says.
