What are genetically modified crops?

Crops that have been genetically modified (GM) are those created with the goal of introducing a novel trait to the species. Resistance to certain pests, diseases, or environmental factors, as well as resistance to chemical treatments, are typically the goals of GM crops (e.g. resistance to a herbicide).

Explanation:

"What would happen to the fat and cholesterol content of your diet if you reduced your animal protein intake? Support your prediction. Option 1: The fat and cholesterol content of your diet would decrease because animal products are typically high in saturated fat and cholesterol. Option 2: The fat and cholesterol content of your diet would increase because animal protein is a good source of healthy fats. Option 3: The fat content would decrease, but the cholesterol content would increase because other non-animal protein sources may still contain cholesterol. Option 4: The fat and cholesterol content of your diet would remain unchanged because reducing animal protein doesn't necessarily affect fat and cholesterol intake."

What does a food web link together?

Answers

Doesnt it link the circle of life?

Victuals webs consist of many interconnected pabulum chains and are more authentic representation of consumption relationships in ecosystems.
The organisms that victual the primary engenderers are called primary consumers. Primary consumers are conventionally herbivores, plant-eaters, though they may be algae eaters or bacteria eaters.
The organisms that victual the primary consumers are called secondary consumers. Secondary consumers are generally meat-eaters—carnivores.The organisms that victual the secondary consumers are called tertiary consumers. These are carnivore-victualing carnivores, like eagles or immensely colossal fish.
Some aliment chains have adscititious levels, such as quaternary consumers—carnivores that victual tertiary consumers. Organisms at the very top of a aliment chain are called apex consumers.

Why are catfish and carp found at the mouth of a river, while trout are found nearer the source?

Answers

Answer:

The correct reason would be "the levels of dissolved oxygen at the mouth of the river and at the source of the river".

The mouth of the river is the region where it flows into the ocean, lake, another river, reservoir, sea et cetera. The level of dissolved oxygen in this region is too low to support great biodiversity.

Organisms like catfish and carp can survive here due to their low oxygen demand. For example, catfish can survive in water with an oxygen content of 2.5 parts per million.

In contrast, the level of dissolved oxygen is higher at the source of the river. Organisms like trout are found here due to their high oxygen need. For example, rainbow trout require minimum 5-6 parts per million dissolved oxygen for its survival.

Catfish and carp require less oxygen than trout. The mouth of a river usually has less oxygen and the area closer to the source has more oxygen, so since catfish and trout require more oxygen they typically are found at the source.
