Question

Fill in the blanks with the correct words. The total number of individuals of a particular species in an area is called __________.

Short answer

The correct word is 'population'.

Step-by-step solution

Identify the Concept

The exercise asks us to identify a term that represents the total number of individuals of a particular species in an area. We need to consider terminology used in biology and ecology.

Recall Terminology

In biology, the term used to describe the total number of individuals of a species in a given area is known as the 'population'. This concept is crucial in understanding the dynamics of species in their habitats.

Fill in the Blank

Based on our recall of ecological terms, we can fill in the blank with 'population'. The sentence will read: 'The total number of individuals of a particular species in an area is called population.'

Key concepts

Species

A 'species' is a group of living organisms that share common characteristics and can interbreed to produce fertile offspring. Scientists use specific criteria to classify and identify different species. These characteristics can include physical features, genetic makeup, and the ability to produce offspring that can also reproduce.

**Interesting Aspects of Species:**

• Species are the most specific level of classification in the biological hierarchy, just below genus.
• The concept of species helps scientists organize biodiversity into manageable categories.
• New species are still being discovered and classified, with thousands identified each year, showcasing the vast diversity of life on Earth.

Understanding species is vital for studying the balance and interaction of life forms. Every species plays a unique role in its ecosystem ranging from predator, prey, decomposer, or contributor to the air, soil, and oceans. Knowing about different species and their roles helps in conservation efforts and in understanding the broader aspects of ecosystems.

Habitat

A 'habitat' refers to the natural environment in which a species lives and thrives. Each species has a unique habitat that provides the essential resources like food, water, shelter, and space to survive and reproduce.

**Elements of a Habitat:**

• Abiotic Factors: These are non-living components such as sunlight, temperature, and soil that can influence the suitability of a habitat.
• Biotic Factors: Living elements such as plants, animals, and bacteria which all interact within the habitat.
• Range and Composition: The geographical area over which a species can be found.

Habitats can be as diverse as rainforests, oceans, deserts, and urban areas. Changes in their habitat can significantly impact the survival of species, due to factors like pollution, deforestation, and climate change. Preserving habitats is crucial for maintaining biodiversity and ecological balance. Each habitat supports a web of life, where even slight disturbances can have ripple effects on wider ecological systems.

Ecology

'Ecology' is the branch of biology that deals with the relationships between living organisms and their environment. It involves studying how various species interact with each other and with their non-living surroundings. This study encompasses complex interactions within habitats, ecosystems, and the biosphere.

**Core Aspects of Ecology:**

• Populations: Groups of individuals of the same species living in a certain area.
• Communities: Different species living in the same area and interacting with each other.
• Ecosystems: The community and its abiotic environment functioning together as a system.

Ecology provides insights into how ecosystems function, how organisms are connected, and the effects of environmental changes on the natural world. It’s essential for guiding conservation efforts and understanding the impacts of human activities like agriculture and urban development. By studying ecology, we learn how to create sustainable systems and restore damaged ecosystems, which is vital for future generations.
