Answer:

Barbasco plant.

Explanation:

Native people in the Amazon rainforest use a toxin extracted from Barbasco plant roots which is responsible to stun fish and make it slow to catch the fish easily. This method is used only on the small streams not on large river. This toxin helps in the slowing of the catfish which can't be catch without of this toxin because catfish is very active and quick which is hard to catch at this state so that's why the Native people in the Amazon rainforest use this toxin.

It not equal in its distribution on earth;but rather varies with the type of ecosystem available and the distribution of biotic and abiotic factors in the ecosystem. For example;

It is highest in the Tropics,due to the species richness and diversity of the region. However, it varies in other ecosystem based on species diversity peculiar to parts of the region .e.g it is highest in the marine ecosystem along the coast of abundant temperature for primary producers.

Why is the mixing of fresh water and salt water in the bay important?
Setler [38]

Answer:

When the salt water is mixed with fresh water,it is called brakish water which have the salinity 0.5 to 35 ppt.

Explanation:

The mixing of fresh and salt water is important for aquatic organisms.

The catadromous fish born in marine habitat but they spend their rest of life in the fresh water where growing and maturation takes place.

Ex- Eel is the common example of catadromous fish.

Like wise,

Anadromous fish born in fresh water and spends their life in the sea and return to fresh water for spawning.

Thus mixing of water is important for breeding and growing of these fishes.

More over, the brakish water contain world's most diversified life forms.

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.
hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

CO_{2} undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

Que energuia produce un huracán
koban [17]

Answer:

Cuando el agua de la superficie está caliente, la tormenta absorbe la energía térmica del agua, al igual que una pajita absorbe un líquido. Esto crea humedad en el aire. Si las condiciones del viento son adecuadas, la tormenta se convierte en huracán. Esta energía térmica es el combustible de la tormenta.

Explanation:

I hope this helps :)
