Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
Answer;
-Northbound APIs
Communication between SDN controllers and routers is governed by Northbound APIs.
Explanation;
-The northbound application programming interface (API) on an SDN controller enables applications and orchestration systems to program the network and request services from it.
-Northbound APIs can enable network functions like path computation, loop avoidance, routing and security. The northbound APIs can also used to facilitate innovation and enable efficient orchestration and automation of the network to align with the needs of different applications via SDN network programmability.
The first organism in the food chain is the producer.
