Explanation

 In an ecosystem, a rabbit is classified as a primary consumer because it is ae

Explanation

The unit of rock that represents all rocks formed during the same geological time scale is a Series. 

Geochronologic Units:

The units of time in the geological time scale are called geochronologic units (e.g., eon, era, period, epoch)

Explanation

 Direct observation methods for tracking mammals have limitations, especially for nocturnal species.

Since these animals are active at night, low visibility makes it difficult to observe them directly.

Additionally, dense habitats and shy behavior further reduce the effectiveness of this method.

Explanation

 Non-invasive Genetic Sampling:

This method involves collecting genetic material (like DNA) from animals without direct contact, for example, through scat, hair, or shed skin.

Applications:

Species Identification: Identifying species based on genetic markers.

Individual Identification: Distinguishing between individuals within a population.

Population Size Estimation: Estimating the size of a population using genetic data.

Genetic Diversity Analysis: Assessing the genetic diversity and structure of populations.

Explanation

 Bilateral symmetry is crucial for an active lifestyle as it allows for efficient movement and better sensory perception.

Organisms with bilateral symmetry, such as humans and most animals, have a streamlined body plan that enhances coordination, directional movement, and faster responses to environmental stimuli.

Explanation

The pectoral and pelvic fins are the paired fins in fishes. 

Paired fins:

Fish have two sets of paired fins: pectoral and pelvic. 

Pectoral fins:

These are located on the sides of the fish, and they are used for steering and maneuvering. 

Pelvic fins:

These are located on the ventral (belly) side of the fish, and they help with balance and stability. 

Unpaired fins:

The dorsal, anal and caudal fins are unpaired and situated along the midline of the body. 

Explanation

The Line Transect Method is a survey technique where an observer follows a fixed pathway (transect) and records bird sightings along the way.

This method is useful for estimating bird populations, species distribution, and habitat preferences.

Explanation

 MOT is widely used in autonomous vehicles, surveillance, sports analytics, and biological studies (e.g., tracking animal movement).

Key Aspects of MOT:

Detection – Identifying multiple objects in each frame.

Association – Matching detected objects across frames to maintain consistent tracking.

Prediction – Estimating object positions in future frames (e.g., using Kalman filters).

Data Fusion – Combining information from multiple sources (e.g., LiDAR, cameras) for more accurate tracking.

Explanation

 The Convention on Biological Diversity (CBD) contains 42 articles along with 3 annexes.

Explanation

 Ineffective in Large Areas – Difficult to cover extensive regions accurately.
