Read the given statements.
(a) Carnivores are called ______ consumers because they get their food ____ from plants.
(b) Fungi and other microorganisms feed on dead matter and ____ the nutrients into soil through process called _______.
( c) Organisms living in very cold environment have deposition of ______ under their skin and are of ______ size.
(d) In submerged aquatic plants, stomata are generally _______ and roots are _______ developed.
Select the option which correctly fills the blanks in any two of these statements.

Options

A. (a) - Primary, Directly, ( c) - Fat, Large
B. (b) - Release, Decomposition, ( c) - Carbohydrates, Large
C. (a) - Secondary, Indirectly, (d) - Present, Well
D. (b) - Release, Decomposition: (d) - Absent, Poorly

Explanation

To solve the question, we need to fill in the blanks in the given statements with the correct terms. Let's analyze each statement one by one.

### Step-by-Step Solution:

**(a)** Carnivores are called **secondary** consumers because they get their food **indirectly** from plants.
- **Explanation**: Carnivores eat herbivores, which in turn eat plants. Therefore, carnivores are secondary consumers as they are one step removed from the primary producers (plants).

**(b)** Fungi and other microorganisms feed on dead matter and **release** the nutrients into soil through the process called **decomposition**.
- **Explanation**: Fungi, as decomposers, break down dead organic matter and return essential nutrients to the soil, which is a critical part of the nutrient cycle in ecosystems.

**(c)** Organisms living in very cold environments have deposition of **fat** under their skin and are of **smaller** size.
- **Explanation**: Fat acts as insulation to help retain body heat in cold environments. Additionally, many cold-adapted animals are smaller in size, which helps them conserve heat.

**(d)** In submerged aquatic plants, stomata are generally **absent** and roots are **poorly** developed.
- **Explanation**: Submerged plants do not need stomata for gas exchange as they are surrounded by water. Their roots are not well-developed since they do not anchor in soil like terrestrial plants.

### Selected Options:
From the analysis, we can fill in the blanks correctly for statements (a) and (b):
- (a) **secondary**, **indirectly**
- (b) **release**, **decomposition**

### Final Answer:
The correct options that fill the blanks in any two of these statements are:
- (a) secondary, indirectly
- (b) release, decomposition
