Ecology Assignment

Ecology is the study of the relationships between living organisms and their physical environment. A community is a grouping of different species in an area, while a population is a single species. An ecological niche is an organism's role, and a habitat is where it lives. Biotic factors are living things like producers, consumers, and decomposers. Abiotic factors are non-living things like water, sunlight, and temperature. A food chain follows the path of energy between animals, while a food web shows complex connections. A biome refers to plant and animal communities in an area with shared characteristics. Biodiversity is the variety of life on Earth. Primary succession colonizes barren land, while secondary succession follows habitat disturbance.

• Population: It is a grouping of individuals of a single species found in an area.
3- What is the difference between an ecological niche and a habitat?

• Niche:  is that organism's role within that environment.


• Habitat: is the place where an organism lives 
4- What are biotic factors? Are living things and factors producers, consumers,
herbivores, carnivores, omnivores, and decomposers.
5- What are abiotic factors?: Are the non-living things Abiotic factors include : water,
sunlight, oxygen, soil and temperature.
6- What is the difference between the concepts of food chain and food web

• Food chain: follow just one path of energy as animals find food.
• Food web: show how plants and animals are connected in many ways to help them all
survive
7- Explain the term biome?: refers to the community of plants and animals that occur
naturally in an area, often sharing common characteristics specific to that area
8- What is biodiversity?:  is the variety of all living things; the different plants,  animals 
and micro organisms

9- What is the difference between the primary and the secondary succession?
• Primary: is the process in which plants and animals first colonize a barren habitat.
• Second: is the process relating to community growth or change that takes place when a
habitat is disturbed or damaged.
10- Define the following ecological terms
a- Ecosystem:  the interaction of the living things with the non-living environment
b- Mortality rate: this means the ratio of deaths to the population of a particular area or
during a particular period of time. Or It is defined as the number of deaths in the population
in a given period of time.
c- Natality rate: this means the number of live births per thousand of population per year.
Or   refers to the number of births during a given period in the population.
d- Immigration: Immigration is the movement of people from one country or region to
another in order to make a new home. Or it is the number of individuals of the same species
