False statement among the given is

Options

A. Habitat includes both biotic and abiotic factors
B. Ecology at the organismic level is essentially physiological ecology
C. Abiotic and biotic components interact constantly with each other
D. Osmotic proteins

Answer

To determine the false statement among the given options, we will analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** Habitats include both biotic and abiotic factors.
**Analysis:** This statement is true. Habitats are composed of both living (biotic) factors such as plants and animals, and non-living (abiotic) factors such as temperature, minerals, and water. Both components are essential for the survival of organisms.

### Step 2: Analyze the Second Statement
**Statement:** Ecology at the organismic level is essentially physiology ecology.
**Analysis:** This statement is also true. The organismic level of ecology focuses on the survival and reproduction of individual organisms, which involves physiological processes. Thus, physiology and ecology are interconnected at this level.

### Step 3: Analyze the Third Statement
**Statement:** Abiotic and biotic components interact constantly with each other.
**Analysis:** This statement is false. While abiotic and biotic components do interact, it is not accurate to say they interact constantly. For example, during certain processes like reproduction, biotic factors may not require abiotic factors to interact. Therefore, this statement is misleading.

### Step 4: Analyze the Fourth Statement
**Statement:** Osmotic proteins include albumin in the blood vessel.
**Analysis:** This statement is true. Albumin is a type of protein found in blood plasma that helps maintain osmotic pressure, which is crucial for fluid balance in the body.

### Conclusion
After analyzing all the statements, the false statement is the third one: "Abiotic and biotic components interact constantly with each other."
